Confirming Functionality and Upgrading a Big-IP

0:01<v ->One of the ways that we can confirm functionality</v>

0:03of our BIG-IP device

0:05is by going into it and looking at some statistics.

0:08So that's what we're gonna do.

0:09Here we are in our BIG-IP

0:11and I'm gonna go up here on the main menu over here

0:13to Statistics

0:14and I'm gonna go down to

0:17Module Statistics

0:19and Local Traffic.

0:21I'm gonna click on that.

0:22It'll bring up our local traffic.

0:23Here we have a Status Summary,

0:25is what it defaults to on our Statistics Type here.

0:28And we see we have two Virtual Servers, two Pools,

0:31three Nodes,

0:32and they're all available over here on the right.

0:35But of course, it'll show you Unavailable,

0:36Offline and Unknown as well.

0:38But that's just saying whether they're active or not.

0:41But what about verifying the functionality,

0:43making sure that traffic is flowing,

0:44like we want it to flow?

0:46Well, at that point,

0:47we can actually click into these things here.

0:50So if I click on Virtual Servers,

0:51it's gonna take me in to seeing the virtual servers.

0:54Okay.

0:55But another way to do that

0:56is if I go back to my Statistics,

0:59modules,

1:00Local Traffic,

1:01let it go back to this page here,

1:03I can come up here to the Statistics Type dropdown

1:05and go to Virtual Servers;

1:07It'll take me to the same place,

1:08you'll see here.

1:09And this is where

1:10I can look at the individual virtual servers.

1:13Here I have my HTTP and my HTTPS.

1:16And I can see the Bits and Packets going in and out.

1:20And we can also see the number of Connections and Requests.

1:23So you can see this at the virtual server level.

1:26But,

1:27that's not always enough, right?

1:29Absolutely not, what about the Pools?

1:31Well, I can go up here and I can go down to my pools

1:34and this way it's gonna load up our individual pools

1:37that are attached to those virtual servers.

1:39And now we can see the same information with our pools.

1:42But, what about individual pool members?

1:44Well, we can expand these

1:46and then see the individual members

1:48and then take a look at our information

1:51about how our transactions, our sessions are being routed,

1:55so we can see how they're being balanced

1:57between individual members of pools;

1:59We can make sure traffic is flowing like we want it to.

2:03And something else we can check,

2:03we can come back over here on the left to Module Statistics

2:06and go down to, instead of Local Traffic,

2:08we can go to Network.

2:10And this is gonna load up our Interfaces

2:12and show us information about those interfaces.

2:16The status being UP or UNINITIALIZED;

2:18UNINITIALIZED, 'cause we're not using it.

2:20Your Bits and Packets, the amount of data flowing.

2:23You got Multicast, any errors that might be in there.

2:25And the Drops, like if you take a look here,

2:27at our management interface,

2:29have 31,000 drops.

2:30There's probably something wrong there.

2:32I should probably take a look at that.

2:34(laughs)

2:35And we saw some of the same information

2:37in the ifconfig command in our Linux terminal,

2:41a few skills back.

2:42But, this is another way to view it,

2:44with in the web UI here,

2:45which is pretty darn handy.

2:47But, guess what?

2:48We can look at this stuff in the TMOS as well.

2:51So, let's go ahead and bring up a terminal here.

2:54This is an SSH connection.

2:56And if you look at this, what does that mean?

2:58Hmm, think about it now.

3:00We've seen this before.

3:01Are we in the TMOS?

3:03Well, no, we're not in the TMOS

3:05because we don't see TMOS in here.

3:07What we're connected to is just the Linux OS, okay?

3:11So, in order to go into the TMOS,

3:13tmsh,

3:14for traffic management shell;

3:16Now we're in the TMOS.

3:17Right there. It's gonna tell us that.

3:20So once we're in the TMOS,

3:21we've got some commands we can run.

3:24Now, I want you to start with show

3:26and hit a question mark.

3:28And these are gonna be show commands, okay?

3:31I don't know what I hit there, but,

3:32I hit something that I didn't intend to.

3:34So, let's do this again.

3:36Let's try the show ?

3:38There we go.

3:39Okay. (laughs)

3:40So, what I wanna show you is Modules.

3:43Really, we have various modules here

3:46and we know that the BIG-IP is a modular system.

3:49We can enable various modules for different features.

3:52Well, when it comes to the TMOS,

3:53and working in the terminal here,

3:56the commands are sorted

3:58by their various modules.

4:00So if we want to see,

4:02let's say statistics of a virtual server,

4:05then we need to know that they reside

4:08under the Local Traffic Manager

4:10'cause that's where we deal with them.

4:11If I go over here to my web UI

4:14and I go under Local Traffic,

4:16that's where my virtual servers reside.

4:17And again, the same thing,

4:19in the TMOS,

4:20they reside under ltm.

4:21So, what I'm gonna see is show ltm.

4:24Now, it's going to show me the,

4:26if I hit a question mark there,

4:28all the components

4:29that reside under ltm.

4:32One of which is

4:34virtual, down here.

4:36So it's gonna show me my Virtual server configuration.

4:38I also see my pool there,

4:40where we looked at the pool information.

4:43So it's just to, kinda get you to understand

4:45that there are modules

4:48within the TMOS

4:48and various commands are nested in those individual modules.

4:52So, if I do show ltm virtual

4:56and hit enter,

4:57it's gonna show me all my virtual servers.

4:59So here's the HTTP virtual server.

5:02It's gonna show me some availability information here.

5:05Destination, Traffic, again,

5:07we're able to see traffic coming in and out

5:10and going various locations.

5:13We also have SYN Cookies for SYN communications.

5:17And if I go down some more,

5:19I see my HTTPS virtual server.

5:21And again, same information there.

5:23Super.

5:24But what if I wanted to dig directly

5:25into one of those virtual servers?

5:27Well, I need to grab that virtual server name.

5:29So let's just grab this in here;

5:31Our HTTPS.

5:32I'm gonna go ahead and copy that.

5:35Hit enter

5:36and I'm gonna Q to exit outta there.

5:39There we go.

5:40What I'm gonna do is hit the up arrow,

5:42show ltm virtual,

5:45and then I'ma put a space

5:46and paste that name in there.

5:48And this is going to put me directly into

5:51only showing me the information

5:53about that one virtual server.

5:55So as we can see,

5:56it looks like the same information here.

5:58And there's a little more down here.

6:00We've got a Message Routing Framework,

6:01we've got some CPU Usage Ratios.

6:04Wonderful stuff.

6:05So that's how we can look at our virtual servers.

6:08But, what about the pools?

6:10Okay, well, we would want to, again, show ltm,

6:14local traffic manager,

6:15and then hit pool in here.

6:18Let's try that.

6:19Okay.

6:20I think it's actually just pool.

6:21There we go, just pool.

6:22Alright, super.

6:23So, what do we have here?

6:25Our HTTPS pool.

6:26And it's gonna go down here and again,

6:27show us a lot of different statistics and information.

6:31If I scroll down, there's our HTTP pool.

6:34So, I'm actually gonna go ahead and copy that one.

6:36There we go.

6:37And I can hit Q to exit outta there.

6:39And as you can imagine, if hit the up arrow command

6:41and I didn't paste the name in there,

6:44it's gonna only show me

6:45that one pool's worth of information.

6:48And that's the same way it worked

6:50when we look at our virtual servers.

6:51But, what if I wanna look at the individual members

6:55of a specific pool?

6:57Well then, what I'm gonna do,

6:58I'm gonna hit the up arrow

7:00to bring up that last command, show ltm pool

7:02and my pool name.

7:03I'm gonna put the key word here, members;

7:06Just like that.

7:07And hit enter.

7:08And now it's gonna show me the individual members.

7:12So as I start to scroll down,

7:13this is my actual pool,

7:15as we scroll down here, there we go.

7:18And, here's my first pool member.

7:21That's my 101,

7:24right there.

7:25It's gonna show me statistics about that.

7:27And as I scroll down, here's my 102.

7:29And I scroll down some more;

7:31There's my 103.

7:32And those are all the members of the pool.

7:34So this is how we can access,

7:36I'm gonna hit Q here to exit outta that.

7:37There we go.

7:38This is how we can access those same statistics

7:40we saw in the web UI

7:41via the TMOS.

7:44Now, we also within the web UI,

7:46if I jump back here real quick,

7:47show you a quick refresher.

7:48We looked at under Statistics,

7:51our modules, we went to network,

7:53there we go,

7:54and that brought up our Interfaces.

7:55We can see that same information,

7:57I bring our TMOS back up,

7:59via the command show /net interface.

8:06There we go.

8:06And we're gonna see here the same information.

8:09Our Status, our Bits, In and Out,

8:11our packets, In and Out,

8:12our Drops and our Errors, all the way.

8:14And you see here,

8:16there's my 31,000 errors

8:18on the inbound of my management interface.

8:22And ah, here we go.

8:23Looks like this one is actually connected,

8:25I didn't see that earlier,

8:26to a hundred meg connection

8:29when I know for a fact

8:30it's connected to a gigabit connection.

8:32So, there's something going on there,

8:33probably a duplex mismatch or something like that.

8:36Something weird going on.

8:38And definitely, I'd wanna dig into that.

8:40All right, super, so that's how to see that.

8:42Now let's hit the quit command.

8:45Let's use that because we're gonna exit out of the TMOS.

8:47Alright, now we're back to just Linux.

8:50So here, what I want to do is go ahead and run the command,

8:55bigtop;

8:56Think about like the circus and here's why.

8:58If I hit bigtop, there we go.

9:00This is our bigip f5lab;

9:04That's our BIG-IP that we're on.

9:06This is our virtual server,

9:08our HTTP and our HTTPS.

9:10And down here, are our members,

9:15right, of our pools.

9:17And that's those six members.

9:19And, what we can do is sit here, sit back

9:22and watch the statistics

9:25of our connections in real time.

9:27And that's why the bigtop is the command.

9:29Think about it like you go to the circus.

9:31You sit back and relax,

9:32you watch the trapeze artist,

9:33you watch the clowns,

9:34and here we're watching the statistics.

9:37That's right!

9:38So you can sit here and watch statistics.

9:40I don't have any traffic flowing right now,

9:42but, we sure could generate some.

9:44So let me do that real quick.

9:45Alright, here I am, on my Windows test box.

9:48I'm gonna open a browser.

9:49And once that comes up,

9:51I'm gonna open incognito window.

9:53There we go.

9:56And go ahead and hit my 172.16,

9:58there we go,

9:59to generate a little traffic.

9:59Now I'm gonna jump back to my terminal here.

10:03And there we go.

10:04I see my one connection now

10:06that's connecting to, actually not that one,

10:08It moved up here.

10:10There it is.

10:11And there we go.

10:12Went to the top.

10:13And that's my server three.

10:14And if I jump back real quick,

10:15you see that server three that I hit there.

10:17So then, back again, if we go to our terminal,

10:19we'll see, that yes,

10:20that is server three, that's our 103.

10:22And so we can actually see the live traffic going in and out

10:25and see which pools and which pool members

10:27are being accessed.

10:29And again, this is within our Linux portion,

10:32not the TMOS.

10:33And we use the command bigtop.

10:34b i g t o p.

10:36And again, think of it like the circus.

10:38You're getting to watch all this entertainment.

10:39(laughs)

10:41Pretty exciting.

10:42Alright, super.

10:43And then one more thing we're gonna look at.

10:44I'm gonna hit the Q to stop that.

10:46bigtop is our good old friend ifconfig.

10:50And again, this is to look at individual ethernet interfaces

10:54and verify things like IP addresses.

10:57So see external, there we go.

10:58We can also look at our errors and overruns

11:01and the amount of traffic coming in and out.

11:04Just a quick refresher on that.

11:05We've looked at if config before,

11:07but, the new ones we've seen include our bigtop

11:11and looking at our virtual servers and pools

11:13and pool members

11:14via the terminal,

11:15as well as of course, our F5 web UI and the statistics.

11:21And this is how we can look

11:22within both the web UI and the terminals

11:26to look at statistics

11:27and identify if traffic is flowing as it should be,

11:30or looking for errors and functionality

11:33within the BIG-IP.

0:00<v Instructor>Let's talk about platform</v>

0:01and software lifecycles,

0:03especially when it comes to upgrading your platforms.

0:07And that's because we need to talk

0:08about both hardware and software.

0:10Now, if you think about it, when it comes to hardware,

0:13so let's say we've got our hardware appliance here inside,

0:15we've got...

0:16Well, we've got CPUs.

0:18That's right, we've got memory, absolutely.

0:21What else do we have?

0:22Well, we've got storage.

0:24You gotta have somewhere

0:25to store whatever software we put on there.

0:28And the thing is,

0:29when this hardware is designed for specific software,

0:33it's designed to run that software.

0:35Now, the thing is, though,

0:37software, what does it do over time?

0:39Well, it changes.

0:40But our hardware is static.

0:44Right, our hardware does not change.

0:46So as software changes, maybe new features come about,

0:52they require more resources

0:56and they can overcome hardware at a specific point.

0:59So the idea is this takes place,

1:02this whole process takes place over time.

1:05And many vendors will only support given hardware

1:08for a specific period of time,

1:10maybe five years or seven years, whatever it might be.

1:14And that's because not only will the software

1:16outgrow the hardware possibly,

1:18well, that hardware gets old.

1:19And what happens to old equipment?

1:21Well, it breaks.

1:24That's right.

1:25Just like vehicles.

1:25When you have a vehicle,

1:27well, the warranties for vehicles

1:30are only gonna last so long.

1:31You're not gonna be able to warranty a vehicle for 20 years

1:33because it's not gonna last that long, most likely.

1:36And there's gonna be lots of parts that break

1:38and will have to be replaced.

1:39Well, the same thing with the hardware platform.

1:42So keep that in mind

1:44as we talk about upgrading hardware and software

1:47because both of them will have to be upgraded over time

1:49when we're talking about platforms.

1:52And just for example, if you think about Microsoft,

1:54well, Microsoft, they have their desktops

1:57and server operating systems,

2:00and they all have various versions.

2:02And those change over time

2:04and they're only supported for so long

2:06and they're no longer supported.

2:07And that's because as a vendor,

2:09you can't support a specific piece

2:10of software forever, right?

2:12Things change.

2:13You're gonna have to drop off the older versions

2:16to support newer versions.

2:18So let's talk about the platform lifecycle

2:22when it comes to the F5 environment.

2:24Well, it starts off with general availability.

2:27When a new platform is designed and put out there

2:30or it could be just a software version,

2:32it's put out to the public to be used

2:34for a specific period of time,

2:37at which point it's no longer for sale, okay?

2:40And this may be,

2:41who knows, it could be five years down the line.

2:44And so that specific product is only sold for five years.

2:48Well, then, that new product is no longer being sold,

2:52but it's still being kept up,

2:54meaning you're gonna have updates that happen along the way.

2:59And at some point,

3:00end of new software support is going to end, right?

3:05So there's no more software support agreements

3:08that are going to be issued.

3:09And then as we continue on,

3:12we're gonna continue with additional updates and upgrades

3:16until end of software development.

3:18And at that point,

3:19there will be no more software development done

3:22on that version of the platform.

3:25And in the F5 world, generally,

3:27there is three years between the time of end of sale

3:31and end of software development.

3:33So it's pretty much standard for three years thereabouts.

3:37And at that point, we enter a different color

3:39in the bar graph you see here.

3:41And that's because this is known as extended support

3:45because it's extended

3:46beyond the end of software development.

3:49And then finally, we have the end of technical support,

3:52which really means, "After this point in time,

3:56you're no longer going to get any kind of support

3:58for this specific version of the platform."

4:01So what do you need to do

4:02during some point during this timeline?

4:04Well, at some point you're going to need to decide

4:06to upgrade to a newer version

4:10because this older version is being sunsetted

4:13or end-of-lifed.

4:14So you're gonna have to upgrade at some point

4:16to get onto a new version of the platform

4:18so that you can stay in this supported area here.

4:21So that's the platform lifecycle.

4:24Now, let's move on and talk about software versioning

4:27within the BIG-IP.

4:29So here, we're starting off with the name BIG-IP,

4:32which we'll see when we go to download software

4:34the name of the OS here we're dealing with

4:37or the software package.

4:38But when it comes to the numbers,

4:39let's talk about what those mean.

4:41Now, when it comes to the numbers,

4:42our major release is gonna be that first number

4:45and our minor release is the second number.

4:48And then we come into a maintenance release,

4:52that is our third number.

4:53And then finally a point release.

4:57And that is the two there, the end number.

5:00So that's our major, minor, maintenance, and point releases.

5:05So when we go in and start looking at these version numbers,

5:07we're going to be able to understand what those are.

5:10Now, let's move on and talk about hardware replacement.

5:14And we've talked about the hardware replacement

5:15as the fact that yeah,

5:17it's gotta be upgraded because as it gets older,

5:20it's only gonna last for so long.

5:22And as new features come out,

5:24they can push the ability of these devices.

5:28So again, we've got to upgrade them.

5:30And as they get older,

5:32the vendors are only gonna support them for so long.

5:34So that's why it's important to understand

5:37how long your device is gonna last for.

5:42And usually, that's referred to as a lifecycle.

5:45And when you're going to go and use a new product,

5:47oftentimes it's very important

5:49to understand the lifecycle of that device

5:52so that you know how long it's gonna last for

5:55so that you can set expectations

5:57to replace those physical devices as time goes on.

6:02Maybe you're gonna replace them every five years or so.

6:04All right, that covers our discussion

6:07over the hardware and software upgrades

6:11and why we're going to do them,

6:12why we need to understand the lifecycle

6:14and the platform lifecycle.

6:16And in the next Nugget,

6:17we're gonna take a look at device upgrade eligibility.

6:20So I'll see you there shortly.

0:00<v Instructor>Alright, it's time</v>

0:01to look at determining device upgrade eligibility.

0:04So can you upgrade your BIG-IP?

0:07Well, let's find out.

0:08So in order to do this, we first need to figure out

0:12what BIG-IP device we have, okay?

0:16And what software version we're running.

0:19So let's jump into our BIG-IP.

0:21Should be right here, here we go.

0:23And let's see.

0:24In order to find this out, I'm gonna go down to system

0:26and I'm gonna go to software management and click on that.

0:29Super.

0:30My product is the BIG-IP.

0:32I know I'm running the virtual edition.

0:34My version is 17.1.0.2, build 0.0.2.

0:39It's also important to go ahead

0:40and take a look at where this is running

0:42and we're gonna talk about this later

0:43when we go through the actual upgrade process,

0:46your boot disc and boot location.

0:48But for right now, let's focus on our version.

0:50And of course, if you're running a hardware device, you need

0:52to figure out what version of hardware you're running.

0:55So there we go.

0:57So we're running our VE or virtual edition in our lab,

0:59but really we're looking at the 17.1.0.2 build 0.0.2,

1:03very important.

1:04So next up we're gonna go over to not there,

1:07but let's try this one.

1:09There we go.

1:10Alright, this is the choose a BIG-IP update

1:14or upgrade version.

1:16So really this is our upgrade guide.

1:19Now if you go through this guide,

1:20it's gonna help you figure out how to do your upgrades,

1:23but we're gonna go ahead and do that anyway together.

1:26So what they're starting you off

1:27with is talking about an upgrade versus an update.

1:30And if we go down here, it's pretty simple,

1:33but you can go and look at this.

1:34So an upgrade, we're talking about various versions,

1:37whereas an update could just be a simple patch

1:40or something like that, okay?

1:43So really what we're looking to start with here

1:45is getting your platform information.

1:48So if you've got a hardware platform

1:49or virtual edition platform

1:51and getting your software version as well,

1:54which we've already done,

1:56then you're going to determine the software versions

1:58that your platform supports, okay?

2:00So for your hardware platforms,

2:01you're gonna go down here and follow this link.

2:05And it's gonna bring this up right here.

2:07This is our, if I scroll back to the top here, hardware,

2:11software compatibility matrix.

2:13So you're gonna scroll down here

2:14if you have a hardware device that is,

2:16and find your hardware device.

2:18And there are several different types of course,

2:20and you're gonna figure out, well,

2:21what compatible software versions can run on my device.

2:25That's gonna let you know if you can update

2:27to a newer version or not.

2:29Now if you can, it's gonna say, hey,

2:31so maybe you're running an i850.

2:33Well then you can run everything up to the latest.

2:35So you're pretty darn good there.

2:38But if you scroll down here

2:39and you're running an older 800, you're stuck with the 14.

2:42So obviously if you wanna go newer, you're gonna have

2:45to upgrade your hardware, alright?

2:47And if I go back then to my upgrade guide,

2:50here's our BIG-IP VE platforms.

2:53Well you can go to your compatibility matrix.

2:57I'm gonna click on this one over here.

2:59There we go.

3:00This is our BIG-IP virtual edition supported platforms.

3:04Super.

3:06And if I scroll down here, you're gonna need

3:08to find your hypervisor

3:09'cause that's really what it relies on.

3:10I'm running VMware 7.0 U3 right here.

3:15So looks like I can run 17.1.X

3:19so 17.1 anything.

3:21So I can run the latest version, which is what I'm running.

3:24But if I was running an older version of ESXi,

3:27maybe 7.0, I would be limited.

3:30And as you can see there,

3:31so I know if I'm running 7.0 U3c

3:35and later I can go ahead

3:36and run the latest, which is what I'm running.

3:38So there we go. Super.

3:39So there's not just VMware though.

3:42If I scroll down here, we're gonna see Linux, KVM,

3:45the Xen Project, OpenStack.

3:47I'm gonna go down, I'm gonna see Hyper-V down here.

3:49I'm gonna see Citrix hypervisor, Nutanix,

3:53you're gonna see your cloud platforms.

3:55So you're talking AWS there.

3:57It's our Amazon.

3:58If I scroll down and see My Azure, keep going,

4:02you're gonna see GCP, Google Cloud, Alibaba,

4:06and the list goes on and on and on.

4:07There's OCI, IBM.

4:09You just need to figure out what you're running on

4:11and coming here and check to see what versions you can run.

4:16I'm gonna scroll back up here to the top

4:18within your virtual environment on your virtual edition.

4:22Super.

4:22Once you've seen that, 'cause there are hardware

4:25and our virtual environments limit what we can upgrade to.

4:28Now once we figure out what we can upgrade to,

4:31we want to go over to I'm gonna click here.

4:34This is the knowledge base article 13845

4:38talking about upgrade paths.

4:42And this is important because depending on

4:44what version you're on and upgrading to,

4:47there are some things you need to know about.

4:49So if I scroll down here,

4:51let's say we're on BIG-IP 17.0,

4:54which we're actually going to upgrade from.

4:55I set up another BIG-IP running 17.0.0,

4:59we're gonna upgrade to the latest version.

5:01And so what you're gonna see here is

5:02let me go back up a little bit.

5:03Versions you're upgrading to

5:05and versions you can directly upgrade from.

5:08Ah, okay, so I could upgrade directly from 15.1x

5:11to 17.1x or 17.0 if I wanted to.

5:15That means this is supported.

5:17However, additional information over here,

5:19you wanna read these notes

5:20because they're gonna save you some headaches.

5:23So again, if this is your upgrade paths,

5:27this is very important.

5:28Can you go from 12 directly to 17?

5:31Well no, but you can go from 12 if you were down here to 14

5:37and then from 14 to 16

5:40and then you can go 16 to 17.

5:43So yeah, if you had something that old, a version

5:46of software that old, you're gonna have

5:47to jump through some hoops,

5:48go through a few iterations of upgrades.

5:51So this is your upgrade pass.

5:53Now once you find out, okay cool, I'm good to upgrade

5:57to the latest 17.1x, alright, got that.

6:00'Cause I checked my,

6:01let me jump back here, my hypervisor

6:04and it supports me going to 17.1x

6:06Super.

6:07So I'm good there or my hardware supports me.

6:09If I go back to my hardware,

6:11my hardware supports me going up to 17.1x,

6:14I'm good there.

6:15Then I check my upgrade paths

6:17and from 17.0 to 17.1x, no problems.

6:21I read through this

6:22and it doesn't look like anything's really gonna mess

6:24with me in here.

6:25So I'm good there.

6:27Now it's time to actually download my software, okay?

6:30And we're going through this process

6:32because this is very important.

6:33You don't wanna just willy-nilly go pick something

6:35to upgrade to or you might end up in a world of hurt.

6:38So if we go over here, I log into MyF5 there,

6:41I'm gonna go over here to resources, go down to downloads.

6:45This should look familiar.

6:46We did this when setting up our labs.

6:47I have read and agree of course, there we go.

6:50Product family.

6:51I'm running the BIG-IP, boom, product line,

6:54I'm running down here.

6:55I'm gonna select that.

6:56It's my BIG-IP 17 virtual edition right there

7:02and a product version.

7:04Now here's the thing, this is what you want to select,

7:07which version you're looking to download.

7:09So I'm gonna look to download 17.1.0. There we go.

7:13And as I scroll down here, I am needing to think about

7:17what I wanna download for an update.

7:19Now here's the thing.

7:20On a virtual edition,

7:21you don't wanna download virtual edition like here,

7:24which is what we did when we set up our lab.

7:27If you're doing an update, it's different.

7:29If you download a virtual edition here,

7:31this is gonna download your OVA files,

7:33your virtual disc files.

7:34We don't want that.

7:35What we want is an ISO

7:37because we're gonna upload an ISO to our BIG-IP

7:40so that it can do the update from the ISO file, alright?

7:43So what I wanna do is select right here, 17.1.0.2,

7:48that's the latest version.

7:50Then I would go ahead and scroll down here

7:52and it's gonna show me my download files.

7:55And what I want is this right here, this ISO.

7:57BIG-IP, I'm gonna select it.

8:0017.1.0.2-0.0.2, iso use for upgrades.

8:05This is what we're looking for.

8:07Alright, super.

8:08The other thing we wanna download is if we scroll down here,

8:11and it's a little tricky, you gotta dig through these

8:12is the MD5 file for this ISO file here.

8:17Now the MD5 is a hash of this file.

8:20So you download the two and you're able to compare them

8:22to make sure that when you downloaded this,

8:24nothing was corrupted or changed

8:25or anything so that you have a clean file

8:27you can upgrade from.

8:28So what I wanna do is go down and find this.

8:31And there it is right here.

8:32This is what I wanna download as well.

8:35This is the BIG-IP 17.1.0.2-0.0.2.iso.md5.

8:40This is the MD5 file for use for upgrades,

8:43does not include the EUD.

8:44So that's exactly what I'm gonna download as well.

8:47And I've already done that.

8:48So once you download those two, we're gonna need to verify

8:51the hash and checksum, okay,

8:54so I'm gonna bring in a terminal

8:56and I've downloaded these.

8:57I'm gonna hit the ls command.

8:58I'm just on my Mac here and this is the ISO file.

9:01This is my MD5 file.

9:03So what I wanna do is on a Mac.

9:05Now Windows is gonna be different

9:06and I'll show you on the Windows the command to use.

9:08So I'm gonna do is md5 and then put BIG and hit Tab.

9:14And there we go.

9:14It's gonna tab that out for me so I can hit Enter.

9:17It's gonna go ahead and generate MD5 hash for me,

9:20which should be the same hash that's in this file here.

9:22My MD5 file.

9:24Here's the hash.

9:25Alright, easy enough.

9:26Now all I need to do is read.

9:28So I'm gonna use the cat command

9:29to read what's in the BIG-IP file.

9:32.md5, not g5.

9:35There we go, there we go.

9:36So this is what's in the file.

9:38So as long as this matches this, we're good to go.

9:43And as I can look, I can see that yes it does match.

9:47So that means I downloaded a clean file

9:48and I can now use this file to upgrade.

9:50This is very important.

9:51You don't want to skip this step

9:53because if any form, way, form

9:55or fashion that that file was corrupted just a little bit,

9:58you could end up in a world of hurt.

10:01But we're gonna show you how to do the upgrade in a way

10:05that you can actually fall back to a previous version,

10:08which is always good in case there was some problems.

10:10But this is a big thing to do.

10:12You need to verify your MD5 checksume.

10:14So if you're on a Windows box, open up a command line

10:18and run the command cerutil -hashfile

10:25then give it your file name.

10:26So I would do my BIGIP... .iso

10:31and then put MD5 at the end.

10:34And that is actually going to run

10:36and generate the hash like we have right here.

10:39Then you're just gonna open this MD5 file

10:43with like a text editor or something

10:45and read the contents,

10:46which you're gonna see are this right here.

10:48And you're gonna compare your hashes at that point.

10:51So this is off, you're on a Windows box.

10:53Okay, super duper.

10:55Alright, there we go.

10:56That's how to go and figure out what you need to download

10:58and your device upgrade eligibility

11:01and of course using your hashes

11:03to verify the checksums of your download.

11:06In the next nugget we're gonna talk about a couple of steps

11:08that you can use to minimize your upgrade downtime.

11:12See you there shortly.

0:00<v Instructor>All right, let's talk about some steps</v>

0:02that we can use to minimize downtime during an upgrade.

0:06Well, the first one is to open a proactive service request.

0:11That's right, so if you're gonna do an upgrade,

0:13well, it's a good idea to go ahead and do this.

0:15So you're gonna go online and you're gonna open up

0:18a new service request for your upgrade.

0:22And this way, you can go ahead

0:24and get in line for some assistance

0:28and your information's already in the service ticket

0:31and you're ready to go

0:33because it's going to give you faster access

0:37to engineers for support.

0:40And that's pretty important

0:41because if you are experiencing an outage,

0:44you're gonna want access

0:45to these engineers pretty darn quickly.

0:47So go ahead and open a proactive service request.

0:50You don't have to wait until you have a problem

0:52to open a ticket.

0:53And if you would like additional help with your upgrade,

0:58you can contact F5's professional services

1:02and they can help you plan out your upgrade.

1:05However, this does come at an additional cost.

1:08But if you don't deal with the F5 a whole lot,

1:11it's kind of a set it and forget it kinda thing

1:13and you just do very little administration of it

1:16and you really want some help with it,

1:18then definitely contact them

1:20and make sure it's within your budget

1:21and you can get some assistance there

1:23so you don't experience some unwanted outages.

1:27So next up, in order to minimize our downtime

1:31during the upgrade,

1:32we need to document what software version we're running

1:34and the disk information.

1:36And when we go in,

1:37we're gonna take a look at this information.

1:39We're gonna go in there and find out

1:41what version of software we're running

1:44and the disk information,

1:46and that's the disk it is running on,

1:48as well as the boot partition, which is gonna be a number.

1:53So it'll be like HD1 is our disk

1:57and then .1 is our boot partition.

2:01And it's very important that we know this information

2:03ahead of time because we're gonna need to use it

2:05during the upgrade process.

2:07So go ahead and document that.

2:09And then lastly, what we're gonna do,

2:11we're gonna schedule a maintenance window.

2:12We're gonna schedule some downtime

2:15so that all of our users out there know

2:18that we're going to be down for an hour or two

2:20or however long during this upgrade,

2:22whatever you feel is necessary.

2:25And that way you buy yourself some time

2:28to troubleshoot issues if they do arise

2:31so you don't have to back out of the upgrade

2:33or update that you're doing

2:35and you can continue through and finish it out.

2:38But it's very important to schedule a maintenance window

2:40because it does take a little while for this to take place.

2:44Now when we do our upgrade a little later,

2:46it takes roughly 15, 20 minutes or so

2:50for the entire upgrade process to happen

2:53and does require a reboot.

2:55So keep that in mind as well.

2:57So when it comes to the amount of downtime

2:59you're going to experience,

3:00it's really going to be determined

3:02by what version you're coming from and going to.

3:05But in our instance,

3:06you'll see it's gonna take 15, 20 minutes or so

3:09if you follow along and do it in your lab.

3:12All right, so those are some steps that we can use

3:13to minimize our downtime during an upgrade.

3:17In the next nugget,

3:18we're gonna start preparing for our upgrade.

3:20So I'll see you there shortly.

0:00<v Instructor>All right, it's time to prepare</v>

0:01for our Big-IP Upgrade.

0:03We've gone ahead and downloaded our ISO file.

0:07We did our MD5 hash check,

0:09and now we're going to perform an upgrade.

0:11Well, not just yet anyway.

0:12We're gonna prepare for the upgrade,

0:14then we're gonna perform the upgrade.

0:15So here we're preparing.

0:17If you take a look at my IP address here, 192.168.121.12,

0:20you'll notice it's different than our Big-IP.

0:22Our Big-IP we've been working on is 192.168.121.11.

0:27That's right, I set up a second Big-IP

0:30and I did that because I needed to install

0:32a version of software that was earlier,

0:35so I could perform an upgrade.

0:36So what I did is install this version 17.0.0 Build 0.0.22.

0:44Okay, good, now we got that straightened out.

0:46Let's go through our pre-upgrade checks.

0:49Now the first thing we're gonna do

0:50is create a backup, right?

0:52Absolutely.

0:53So in the Big-IP world, this is called an Archive.

0:56So in order to create an Archive,

0:58what we're going to do is,

1:01we're going to go to System, which is right here,

1:04the bottom left, and then go down to Archives.

1:07There we go.

1:08And I have none in here.

1:10This is a new install, that's why.

1:11So what I'm gonna do is click

1:12on the Create button on the far right and Create,

1:15and I'm gonna give it a name.

1:16I'm gonna say BigI that's there, BigIP2-config.

1:21Now, how about we go with that?

1:22Encryption, I'm not gonna encrypt it.

1:24Now if I was in production, I would.

1:25All right, super.

1:27And it shows me the version here that I'm running.

1:30So go ahead and click Finished.

1:32And it's gonna go ahead

1:33and create that Archive or Backup.

1:36Now again, this Archive contains everything you need

1:39to get back up and running with all your Config Settings,

1:42all your Certificates, all your Keys, all that stuff.

1:46All right, super.

1:47It says status is okay.

1:49So I'll say, OK here.

1:51Now, I can go ahead and click on the name here.

1:53Let's click on that, it's gonna take me into it.

1:55And I can click on the Download button right here.

1:58So I'm gonna click on that.

1:59So now I'm downloaded.

2:01There we go, super.

2:02My Backup, so I have my backup now, so I'm good there.

2:06So we got a Backup.

2:07Next thing we need to do is jump into the TMOS.

2:09So now I'm gonna bring in a terminal here.

2:11There we go, super.

2:13And you see we're in Big-IP2

2:16and I'm in the Linux here.

2:17So I need to go ahead and jump into the TMOS.

2:19So let's do that.

2:20Let's TMSH on over there.

2:22Excellent.

2:23I'm in the TMOS.

2:24Now the command I want to run is load/sys.

2:28There we go.

2:29Config verify.

2:31Now let's talk about this.

2:32What we're doing is loading the system configuration

2:35and we're verifying it.

2:37We're not gonna make any changes.

2:38All we're doing is letting the Big-IP go through

2:40and verify the configuration

2:42to make sure there's nothing in there

2:44that's a misconfiguration

2:45that might cause a problem with the upgrade.

2:48That's all we're doing.

2:49So I'm gonna hit Enter.

2:50It's just going through and verifying the configuration

2:53of the system to make sure there's nothing

2:54that might cause a problem with our upgrade.

2:57And as long as we don't get any errors, then we are okay.

3:01And usually this just takes a few seconds and there it goes.

3:03No errors, so we're good to go there.

3:05So we checked our configuration, that's awesome.

3:08Now, something you might have to do is to go ahead

3:11and reactivate your license.

3:14And that does force a reload of the configuration,

3:17which is fine.

3:18But if you do get prompted

3:20or for some reason need to go ahead

3:22and reactivate your license,

3:24there's a couple different ways you can do it.

3:25So we can actually run a command here from our TMOS

3:29to go ahead and do that.

3:30And the first command we're gonna run though

3:32is show/sys license.

3:37There we go.

3:38And hit Enter.

3:39And here is my license.

3:41So I'm gonna copy that, just like that, excellent.

3:45And it shows you your active modules

3:46and such in there, super duper.

3:48And I'm gonna hit Q to end that.

3:50Now to actually reactivate this,

3:52so I just did the Show Command,

3:53which was this one right here,

3:55so that we can show the license so we can copy and paste it.

3:57Now in order to reactivate it,

3:59what I'm going to do is use

4:02the command install/sys

4:07license registration-key

4:12and then paste that in there, just like that.

4:15And it's gonna go through and reactivate that license.

4:18Super, so if that's how to do it via the Terminal.

4:20So it just finished, it says, New License Installed.

4:23That's just really, it's just going out

4:24and verifying that you own the license.

4:26It's a real license, it's checking it now.

4:29It's restarting our SNMP service.

4:30So let me move that out of the way.

4:32All right, so again, if you're gonna do this via the WebUI,

4:35now, we wanna go to System and License.

4:36So if I'm down here in System,

4:38I wanna go down here to License right here.

4:42Click on that and we see the License here.

4:45All we would do is click on the Re-activate button

4:47down here in the bottom left.

4:49It's that's simple and we don't need to do that,

4:51'cause I just did it via the Command Line instead.

4:54So there you go, that's how to do it either way.

4:56And now, we are actually ready to do the upgrade.

5:00So we've done our preparation,

5:01we did our backup or archive,

5:03so we have a copy of all of our configurations and stuff.

5:05We went through and we verified the config

5:08to make sure there are no errors,

5:09and then we went ahead and reactivated the license.

5:11And again, we are now ready to do our upgrade.

5:14So we're gonna start that in the next nugget.

5:16See ya there shortly.

0:00<v Instructor>It is finally time</v>

0:02to perform our upgrade on our big IP,

0:04and that's what we're gonna do.

0:05So I'm here on my big IP.

0:07This is our big IP-2,

0:09and that's our 192.168.121.12.

0:11And if I go to my, down here under system,

0:16and I go down to software management and click on that,

0:18it's gonna show me I'm running version 17.0.0,

0:21build, 0.0.22.

0:24This is very important here.

0:25I'm running on disk HD1, boot location, HD1.1.

0:31Again, very important.

0:32You need to record this, okay?

0:34Super. All right.

0:36So what's the first step?

0:37Well, first step is we've already downloaded our ISO file.

0:40We did our MD5 checksum comparison.

0:43So now it's time to upload this ISO

0:46so that we can have it here and upgrade it from.

0:49So I have zero available images here,

0:52so I can't upgrade from anything.

0:53So what I need to do is go over here to the far right

0:54and go to import.

0:56Excellent.

0:57Choose file.

0:59I'm doing my ISO file, and there's that MD5 file

1:02we used to check our checksum.

1:06So I'm gonna say open, and I'm going to say import.

1:10Now it's gonna go through the process of importing it.

1:12I love that it gives you a progress,

1:14lets you know you know how you're doing.

1:16Super.

1:17So it's gonna go ahead and upload the ISO file.

1:20Once that is complete, I'm gonna jump back in here,

1:24and we will continue with the upgrade.

1:25So I'll see you there here shortly.

1:27I'm just gonna pause the video.

1:29Okay, I am back,

1:30and you'll see it's only a 10% right now.

1:32But what I wanted to show you is

1:33I'm gonna bring in a terminal here,

1:35and we are in our Linux here.

1:37So I'm gonna jump over to our traffic management shell,

1:39our TMOS operating system.

1:41There we go. Super.

1:42Now what I wanted to show you is a command,

1:44and that is list forward slash sys software image,

1:50and hit enter.

1:51There's nothing there.

1:52That's right.

1:53This is a way via the TMSH

1:55to check your software images that are available.

1:58Now once this completes its upload,

2:00we're gonna run this command again,

2:02and I should then see my ISO file in there

2:05so that I can upgrade to.

2:06So I just wanted to show you that real quick.

2:08I'm actually gonna go ahead and re-pause this,

2:10and we'll be back when it finishes.

2:12All right, we are back, and the upload has completed.

2:16Once it completes, it goes back to this screen here,

2:18and it shows us a nice check here,

2:21and we have our software image.

2:23I'm gonna actually go ahead and copy that real quick.

2:25There we go.

2:26And it shows this as version 17.1.0.2,

2:29and the image size is a BIG-IP image verified and available.

2:34Super duper.

2:35Now what I'm going to do is bring back our terminal here,

2:39and I'm just gonna hit the up arrow and hit enter.

2:42And now we see we have our software image here

2:45available for use.

2:48Let me move this down just a hair.

2:49There we go.

2:51So this is the name here, right there,

2:53and that's important,

2:54so we're gonna need that here in a minute.

2:57All right, super.

2:57Let's go back through here.

2:58Now, what is next?

3:00Well, now we uploaded it,

3:01and you can do this ahead of time, of course.

3:03You don't wanna wait 'til the time of upgrade to do this.

3:06So during your preparations, you're gonna go ahead

3:09and upload so it's ready to go for your upgrade.

3:12So what we're going to do now is install it.

3:15Pretty straightforward.

3:17So I'm gonna go ahead and click on that

3:18and click the install.

3:20And now I have a popup window.

3:22So it says here, select disk HD1.

3:24That's what we're gonna go with.

3:26And volume set name.

3:28Now what we're gonna do is put a number in here

3:30and I'm gonna put number two, and I'll tell you why.

3:32If we look up here under the boot location, it's HD1.1,

3:37and that means it's on a volume set called one.

3:43HD1 is the hard drive, dot one is the boot volume, okay?

3:50So what we wanna do is put number two in here

3:52because by doing that, it's gonna create a new boot volume,

3:56and it's going to install this to the new boot volume.

3:59That way we have the old operating system

4:01on one boot volume, the new on another.

4:03So if something goes horribly wrong with the upgrade,

4:06we can always boot from the old system.

4:09So keep that in mind, very handy.

4:11Now, I'm not gonna install it just yet

4:13because I wanna show you,

4:14you can do this from the terminal as well.

4:15So here we go.

4:16So let's slide this up.

4:18Now, what you wanna do is we copied this up here

4:21'cause you're gonna need that.

4:22The command you're gonna do to install this

4:24is install forward slash sys, space, software, space, image.

4:29I'm gonna paste in the image name.

4:31Then I'm gonna type volume HD1.2,

4:36two is the new number, space, create dash volume.

4:41And that's because it's gonna create that new volume two

4:44on hard drive one.

4:45And I see that I actually typoed that.

4:47It should be HD, not DH.

4:51There we go.

4:51So that's how you would do it from the command line

4:54if you wanted to, but we're not going to,

4:57we're gonna do it via the web UI

4:58so you can see what that looks like.

4:59But I wanted to show you the command so you know what it is

5:03and that you can actually do that.

5:05So there you go.

5:07Now let me go ahead and get rid of this command

5:10because we're going to go ahead

5:13and start the process on the web UI,

5:17and then I'm gonna show you a command you can use

5:19to look at the process status from within the terminal here.

5:24So let me move that outta the way.

5:25All right, so we're gonna go ahead,

5:27and we're back here in the web UI.

5:28We've got this set HD1.

5:30We're gonna use volume set name two,

5:32and I'm gonna click install.

5:34And now it's going to start the install process,

5:39and it's installing it

5:41but it's not showing me anything here.

5:43So what I want to do is show you a command you can run

5:46that I was gonna show you anyway from the terminal.

5:48And here it is.

5:49Show sys software.

5:51And if you look down here, it says HD1.1.

5:54This is active and running.

5:57Status complete.

5:57But if you look at the next line, HD1.2, BIG_IP.

6:01This one here is in the process of installing, all right?

6:06That lets us know that it is installing.

6:08There we go.

6:10All right, super.

6:10So now we just kind of give it some time

6:12to finish installation.

6:15So, I'll be back.

6:17All right, we're back.

6:18It's still installing,

6:19but you'll see now that the BIG-IP has a little clock here.

6:24And over here under install status,

6:25we have a progress bar.

6:29And I was a little confused

6:31because I didn't see the progress bar I was expecting to see

6:33'cause I've seen it in the past from doing upgrades.

6:35So what I did was, for some reason, it just didn't refresh.

6:39So I just went simply back to system, software management,

6:42and it refreshed the page, and it showed up.

6:44So I just wanted to make sure to show you that

6:46because for some reason it didn't

6:47just automatically pop up, which it normally does.

6:49Interesting.

6:50All right, so I'll be back when this finishes.

6:54All right, we're back and the upgrade has completed.

6:58Now here's the thing.

6:59Remember, we created a new boot sector,

7:03which is number two on HD1.

7:05And if we look up here at our images installed,

7:08our installed images, we see our currently running HD 1.1,

7:13'cause we haven't rebooted or anything.

7:15We're on there, old 17.0.0, 0.0.2.

7:19But on our HD1.2 sector,

7:22we've got 17.1.0.2, 0.0.2, which we just installed.

7:26However, it's not active.

7:28So if we look at the active column here,

7:29we can obviously see it's not active.

7:31Now, the default boot is set to the old image,

7:34which is fine.

7:35So what we want to do, we wanna go over here

7:38to boot locations at the top.

7:40We're gonna click on that.

7:41I'm gonna go and click on the link for my HD1.2.

7:45Click on that.

7:46All right, so here we are in our boot location, HD1.2,

7:51and we can see the version it's running is 17.1.0.2, 0.0.2.

7:58All right.

7:59And under install configuration,

8:01now keep in mind, we just installed, from an ISO,

8:05a blank 17.1.0.2 version, okay?

8:09So there's no configurations on it.

8:11So if we went and just clicked on Activate

8:13to make this the active boot location,

8:16it's going to reboot and boot up with 17.1.0.2

8:19but no configurations.

8:20That's not what we want.

8:22So install configuration, we wanna move that to yes.

8:24And then for our source volume,

8:27we only have one option here, HD1.1,

8:30which is running 17.0.0.

8:32And that's fine.

8:33That's what we wanna select

8:34because it's gonna pull the configuration

8:36from our source volumes.

8:37Now all we have to do is click Activate,

8:39and it's going to then go ahead

8:41and reboot into the new image.

8:45So let's go ahead and do that.

8:46Activate.

8:47And are you sure you wanna do it?

8:48Yes please. Thank you very much.

8:50So it's gonna receive the configuration

8:52from our device now, and then it's gonna go ahead

8:54and do a reboot and come up on HD1.2,

8:58running 17.1.0.2, 0.0.2.

9:02So I'm gonna go ahead and pause the video here

9:05and let it do its thing.

9:07Okay, I wanted to show you this

9:09because it just switched to this screen.

9:11This is our BIG-IP2.

9:12It says, "Please wait while the device reboots."

9:15And it's going through and shutting down services and such.

9:18So I'll come back when it's finished and time to log in.

9:21All right, we are back.

9:22And as we can see here,

9:23it says, "Start up in progress. Reboot complete."

9:26So we can now log in.

9:27So let's go ahead and do that.

9:28Log in admin, put our password in.

9:31There we go. Super.

9:32And it's booting up here.

9:35All right, and we'll give this just a minute.

9:38Super.

9:39Let's go down to system.

9:40Let's go to software management, and let's take a look.

9:44All right, so as we can see here,

9:47BIG-IP is 17.1.0.2, 0.0.2 on HD1.2 is now active

9:53and the default boot.

9:55Super.

9:56But if we wanted to, we could boot back into our old version

9:59if we wanted to for some reason.

10:01Maybe we had a problem with booting

10:02into this one at some point.

10:04And there you go.

10:05So what you could do is go down here

10:07and go ahead and delete that image, that ISO,

10:10'cause we don't need to keep the ISO on there anymore.

10:12I'm gonna go ahead and delete that.

10:14There we go.

10:15And it's simply 'cause again, we don't need it.

10:17We used it to create our new boot location

10:20so it's no longer needed.

10:21Super.

10:22So that was a successful upgrade to 17.1.0.2 from 17.0.0.

10:29Now I do wanna show you real quick,

10:30I wanna bring a terminal in here.

10:32If there were problems during the upgrade,

10:35there is actually a log.

10:36So if you do ls, this is just in the Linux partition,

10:39not the TMOS, ls/var/log, hit Enter.

10:43The liveinstall.log right there.

10:46So what I'm gonna do

10:47is cat /var/log liveinstall.log, pipe more.

10:54It's gonna let us scroll through it.

10:55Hit enter.

10:57And here you go.

10:57This is the log it created from installing the upgrade.

11:00So as you can scroll down and take a look,

11:03it's adding various packages

11:05and doing all this fun stuff for us.

11:08It's going through and doing all these things.

11:09You can see all the activities

11:11so you could see any errors in here,

11:13but of course you'd wanna contact support

11:16for assistance with a failed upgrade.

11:17But I just wanna show you that this log does exist

11:20and whatever it is and what it is called.

11:22So that's how we perform an upgrade on a BIG-IP.

0:00<v Instructor>All right, sounds like your manager</v>

0:02has assigned you the task of figuring out

0:04what the latest version of the BIG-IP software

0:06you can upgrade your BIG-IP to.

0:09And your office has a standalone BIG-IP 7055s type

0:13D 110 device.

0:15And it's currently running version 16.0.1.

0:19So what is the latest version of software we can use?

0:23So we're gonna need to use

0:25our hardware/software compatibility matrix.

0:28And we were given the information we need.

0:30We're running a BIG-IP 7055s.

0:33So let's go down here to the hardware and find that.

0:36And basically the best way to do this

0:37is just do a control F or search for it.

0:40So we're gonna do 7055s.

0:43There it is.

0:45All right, so now that we have that, let me close that out.

0:48We know that's right there.

0:49If I scroll up here,

0:52and our compatible software versions is at the top,

0:55we can see that we're running 16.0.1 is what we were told,

1:02and that's in here.

1:04So we can upgrade to 16.1.3, but it doesn't look like

1:08we can upgrade to anything in the 17 family.

1:11So it sounds like 16.1.3 is the latest version

1:16of BIG-IP software that we can run

1:20on our physical BIG-IP appliance.

1:23Now, how would we get to 17 if we wanted to?

1:26Let's say there was some new feature

1:27that we really wanted in 17.

1:29Well, we would have to upgrade to a new device.

1:31So, of course, we have to go through that process.

1:35But once you get the new device in place,

1:37well, you would have a newer type,

1:39so you'd be able to run version 17.

1:43So there you go, that answers our question.

1:45The answer is 16.1.3 is the latest version

1:48we can run on our appliance.

1:51I hope this has been informative for you,

1:52and I'd like to thank you for viewing.
