Thanks for the suggestion, but there is no 'show name' command in the CLI for the Aruba Mobility Access Switches. There is for the HP-branded equipment - we have 5412 and a 5406 - and I use 'show name' frequently on those. I wish the MASs had it, but at last check they do not.
The best I've been able to come up with is this:
show running-config | include "/0/0,**"
This only works because when I put in a description for an interface, I always put a couple of asterisks at the beginning and end of the description, i.e.:
(Aruba MAS) (config) #interface gigabitethernet 3/0/0
(Aruba MAS) (gigabitethernet "3/0/0") #description "**Drop M-207, Rm. 230**"
