I purchased some SFPs to go in to a Cisco 10GB switch, and found they did not work in my switch. While investigating the fault, I found some useful commands to help me.

These commands seem to work on both Cisco IOS and the Nexus switches, alebit with some slightly different syntax.

Show Inventory - sh inventory displays information about the switch hardware options:
