Recently fellow champion Ioannis Theodoridis asked around how to find out what SNMP MIB’s are supported by a specific Cisco network device. And although model driven telemetry is gaining momentum, many monitoring systems still rely on SNMP. And finding those MIB’s can be a challenge. I found out a very easy method to quickly find which MIBs are supported.
To get started, you need your CCO credentials by hand and an outbound FTP client. In this blog I’m using the terminal app on my mac.
1. Connect via FTP to ftp.cisco.com and login with your own CCO credentials, set FTP to passive
2. now go to the directory “/pub/mibs/supportlists”
3. Do a directory listing (long) and enter the directory for your device. The device listing is long, I selected a new Cat9k switch in this example
4. Do a directory listing and fetch that HTML file and logout
5. Open the HTML file in your favorite browser and voila, you have the supported MIB directory for that network device type
Below are two samples of the supported MIBs for the Cat9300 family and the Nexus 3000 family.
I have found this method very easy to find which MIBS are supported by any cisco device. It is an easy way to get that comprehensive list of supported MIBs. If you want to download them for your own NMS, you can go to the SNMP Object navigator and download the supported MIBS as next step.
