I'm trying to learn my way around Cisco switches by watching an online course [1] and trying the commands from there on a switch I have access to. One of the first commands I've tried, show vlan brief
, doesn't seem to be supported on the switch I tried it on. Could you help me to figure out why is it so? Do different versions of IOS have different ways of configuring VLANs? Or my switch doesn't have this feature enabled? Or maybe I'm doing something completely silly, and is not in the right mode or something?
Here's output from the console:
