Hi, my name is Cyndie, I'm from the Dell Networking Team, and today I'm gonna cover
the post upgrade validation, what can you check to make sure everything is running fine, is there
any issues with the the upgrade? Aside from the straight out like the upgrade failed this is more
if the upgrade was successful so now you just want to run some validation commands on the switch.
So I'm going to log into my chassis and I'm going to SSH over to the management module,
the lead, because I'm going to connect to the a1 switch in my lead chassis.
You're gonna use your credentials that you do for OMEM, there we go.
Before I run the commands I just wanna show you my topology. So my
my a1 switch is in my lead and then my a2 switch is in my backup and these chassis are grouped.
Once you are in 'racadm connect' and in this case we're going to switch one which is the
a1. The type of commands that you want to run, I mean the first one is the obvious one, you're
going to run 'show version'. After you verify the version is correct, and in our case it's 10.5.2.4
which is our latest currently, you're going to want to check out the SmartFabric. So you have
'show smartfabric cluster', so this is currently our SmartFabric master. You're going to run
'show smartfabric nodes', this is going to tell me all the switches that are in my cluster. So we
have two and I could see that they're online and I could see that one's in a1 and the other's in a2.
Then we would run to see that all of our networks, the database of the VLANs is
learned on our switches and they are. So because in the MX7000 it's a layer 2 fabric you're going
to go through and look at your VLANs. So all the ones that I've configured in my chassis
are listed. I did have a lot more in my database but I did not configure them in my
server templates or in my uplinks. Another command that's really handy is checking out the uplink, so
we see here that my port channel 6 is up. Its an LACP, and it's active, that's what the 'p' means.
Once you've verified that the networks are up, the uplink is up, the SmartFabric is up,
the last thing I usually double check is the health of the VLTs. I would run the 'show vlt'
commands which would be the 'show vlt 255' because that's the domain name of my VLT
and I could see here that the port channel 1000 is formed because it's showing up and
then also I have other information about the the peer unit id. Everything looks good.
There is one more command that should be run, and this should be done after
you've updated both switches because they might depending on your upgrade steps if you're doing
stepping. Most of the time you're not going to see any mismatches, if you do see a mismatch don't
worry about it as long as it doesn't seem anything blatantly wrong with the VLT everything should
be good. Those are the commands that you would run to make sure SmartFabric is up and running.
The other place you could go verify the fabric health would be in OMEM, and this is
what a lot of people use. You'd go to 'Devices', 'Fabric' and then you would double check that the
fabrics state or health is green and we do see that. You could go click on this, the fabric,
and you could look at the uplinks and again we're still seeing green.
Another place to look at at the fabric health is through the topology. You get a nice visual
of the fabric, you could see if there's any ports down. In our case all of our ports are up. It is,
these are our, all of our ports for our uplinks, so everything in this view is right.
And that's pretty much it. Those show commands are very helpful
if you want to check the overall health. and that really concludes my video.
Thank you again for watching.
