Hello and welcome back to Sai Berries Infrastructure Services. This is trendier when we're gonna be upgrading the Cisco switch IOS today.
So today we're gonna learn how to go. Francisco IOS. We're gonna look at a few different avenues,
and eventually we will be utilising t ftp to push the
image under the switch.
So a couple of recommendations for you Oh, great. You should make sure that the device meets the memory requirements for that Iowa's, for example. You'll see in the video I actually had to go grade my ram on that and also the flash because I didn't have enough room to put all that anyway. S a version on there.
You got to make sure that all the feature sets that you're currently using our
supported in the new IOS as well. And make sure that you get the same feature Said's.
Lastly, you need to make sure that you have enough from the flash
because the flash that is currently on my switches about 32 megabytes and
each IOS is about the 27 30 megabytes. So I had to go through out and delete the Ben file and then t ftp the new Ben efi onto it,
just in case. Nowhere to how to do recover procedures, cause I actually, this video got delayed a few days because I had to send over my IOS at 9600 bod
because it's went into recovery mode. So just know where those materials are. There's a link for the one that I used. It kind of just goes through
and shows you how to do it, you know, in a recoverable, slowly doing over X modem
that further it do, let's go ahead and get started a little bit. So we're gonna back up the old IOS.
So I am going to bring over
the party session here. No. Ah,
bring on the bloody session
and was doing a show flash.
It's verified that been follow a wants here.
Okay, so, uh, copy this
She ftp the servers on?
And just nation foul name
and let's send it over.
So did go through and verify that my server is listening. Before I did this,
it sure used the Net. Stat Command Austria while this is going here,
uh, you All right. Here, use the stats. You
for UDP all listening and a miracle. Because if you don't use it in a miracle, remember, it's trying to resolve all these I p address to host names
on here. We can verify that it is listening.
So let's see how far we've gotten here.
You can actually check on
here, Do it. Ls my cell
little bit coming over. Absolutely.
Yeah. You see, it still is incriminating, so
we'll go ahead and pause a video, and I will resume it once you finish here.
All right, so we're gonna get in your here. You see, we've gotten almost 10 megabytes. It's, uh,
is taking its sweet time over a couple serial links. Um,
sure. What's runs so slow? Could just be the VM here as well.
We're gonna continue somebody go ahead and back up the current config. What we do here, I'm actually gonna ssh into the switch.
Uh, if I remember right here.
Able to copy. Run Flash
caught running. Back up, Dr Fig.
All right, so I'm actually gonna start t ftp server here,
and then we're gonna copy over that config. Guns, put it on the correct interface here,
and let's go ahead and send it over. So it's a copy flash,
and we want to you running and thick backup t ftp
once a to 16. $1.50.
And copied over. Quick enough.
This one still going slowly.
All right, so if you just do a show flash here,
I could see we have 70 million was free. Um,
versus sorry. Just about 13 megabytes.
7 15 file is actually
a little too big for it.
this one? Right here.
All right, so we have back to current fig. We've verified our teepee access. Where to go? So what we're gonna do know is copy the the upgraded image to the device from TTP.
We're gonna go ahead and close out. Today's lesson will continue this in part to the next video.
For now, let's go ahead and do a small quiz question here. So what? Is it not a common way to push a Cisco IOS upgrade
give you a few seconds to think about it.
All right? If you chose cereal,
that would probably be the most corrective you did. You have to create an Iowa Esther CEO connection or Obata rate. You're gonna be there for quite a long time. Http also isn't very common set, except that as well.
Otherwise we'll go ahead and get at the summer here. So today we kind of went over some prerequisites and we started to go over the Cisco Wireless
upgrade process. The next video. We're gonna go ahead and finish up this lesson and we'll get everything upgraded.
