Nexus and IOS commands

Second Post: Two cool commands I learned today. The show interface capabilities command I ended up having to use it becasue I could not apply switchport trunk encapsulation dot1q to a interface. Once I issued show interfaces capabilities module X I was able to tell why. It only supported 802.1Q trunking so there was no need to specify it. I was googling some stuff about UDLD and I came across show errdisable detect so I figured I would share it.
