Lastly,
we're going to wrap up this section by exploring SNMP
management of a Cisco iOS device.
You'll recall,
we have that cloud services router running in the Azure cloud on this
same network and it's not really doing anything,
it's just there as a demo, that's why I put all this together,
but we can still manage it,
we can still see what options are available to us for Cisco devices.
So let's go here to the All Devices list and I know that
our router has the IP of 192.168 .150 .7,
so let's see if it's discovered it so far.
There is the .6 and it says it's an unknown device.
So let's go see if we can do a little bit of discovery on this guy.
So we'll click on this and we'll change some of the settings to
reflect the correct information about this device.
So we'll go over here in the settings and rename the guy first off.
So we'll say it's going to be GLOBO-Router and we scroll down a little bit
and we can give it a lovely little Cisco icon and we're going to go down
and change the credentials for SNMP devices.
It defaults to public, even though we set it up at the root.
So we'll say it's GLOBO-RO, and we'll hit Save.
So now that we've done this,
we go back to the Device page and I'm going to actually click the
button to do the recommendation for additional sensors.
So we'll let this run for a little bit and we'll see
what it comes back and recommends.
And unlike the Windows box, it actually recommended six total sensors for us,
so Uptime SNMP Traffic, etc, so we'll add all of them.
And we wait just a moment and let it appear in the sensor list,
and once it does a couple of polls,
we see that we're now getting statistics on 2 GB ethernet interfaces.
That's all I could put into this virtual router,
and as well as the HTTPS interface four configuration because,
again, I just put a very basic config on it and didn't disable HTTPS,
as well as the CPU and memory and the up time.
The system has been up for 2 hours and 18 minutes.
Now when it comes to monitoring Cisco devices,
especially Cisco switches,
it's very tempting to look at all 48 switchports and go
well I'll need to monitor all 48 of those.
Take it from me, friends,
only monitor the ports that connect to devices that you know need to be online,
things like wireless access points, other switches,
the uplinks to other switches and routers,
any kind of always on devices like ATMs in a financial
environment or display boards in a call center environment
because if you monitor all of your end user ports,
I can tell you you're going to be driven to distraction by
all of the up/down alerts that you get as people come into
the office and leave the office.
So just for curiosity,
let's see what other sensors we can add on the Cisco router side.
So let's say Network Infrastructure and we will say we want to use SNMP,
and so there's the Cisco IP SLA where you can monitor the IP SLA
tests that you can configure on your Cisco router.
There is the ASA MIBs,
which are completely different from router and switch MIBs.
We've got class-based quality of service,
and all of these wonderful little pollers that are built into the system.
And so,
that pretty much wraps up our discussion of configuring Cisco
devices in the network management system.
Towards the end of the course,
we'll give some various best practices surrounding network
monitoring systems and some of the dos and don'ts that I've kind of
learned over 20 years of monitoring networks, but that concludes this section of the course.
