Monitor Cisco Devices

[Mike Tuggle]

I know there have been a lot of threads about compiling cisco mibs but I have a little different question. I want to monitor basically up/down. I would like to some how change the SYSTEM TYPE from Unknown to Networking. Any suggestions on how to do this? If there is currently an easy way to load the mibs I will do that but from what I have read that is not exactly an easy task.

If you look in Options --> Discovery --> Manage Systems Types you'll see a number of Cisco devices that have rules to be automatically recognized. It looks like hpSIM is looking at an SNMP OID of 1.3.6.1.4.1.9.1.x with the last number being a unique value for each of the Cisco devices.

Thanks for the input. I have seen those but the mibs listed are mostly routers which is great but I also have a bunch of Cisco Catalyst switches that are not listed. Any suggestion on how to monitor those?

Look above at my previous post. The SNMP OID is being used to uniquely identify each CISCO device:

1.3.6.1.4.1.9.2.40 = Cisco 1000
1.3.6.1.4.1.9.2.41 = Cisco 1003
1.3.6.1.4.1.9.2.44 = Cisco 1004

What you're looking for is a unique OID that can identify the device. In the case of the devices above, apparently the presence of the OID itself is unique to the device (the device type manager isn't looking for a particular value, just anything). I don't have a Catalyst to play with, but maybe someone else out there does. An SNMP browser could be helpful in viewing the data available at various OIDs. Once you have something that you can use to identify it, you have your rule and you can plug it in.

Thanks I believe I just got what you are talking about. You are saying to find the OID string and just create a new rule. That sounds easy enough. Thanks for the help.
