Adventures with SNMP and Cisco Nexus (Part 1)

I’ve recently been working with the Splunk SNMP Modular Input and some Cisco Nexus switches to see what sort of data and information I could gather using just the SNMP collector.

It has been an interesting exercise. We were able to get access to Cisco’s product labs where I could (remotely) access some of their high-end hardware, and I was able to test the SNMP collector against the Nexus series 3000, 5000, and 7000 switches.

Lots of devices use SNMP, and the MIBs which I’ll discuss below are relatively universal among switch/router devices, so consider this a practical example of working with SNMP data in Splunk, and some lessons we learned along the way.…
