Hi, Madani - as far as I can tell, the output from 'show lldp neighbor' shows only APs and phones - not the switchport at the other end of an uplink. If I specify 'show lldp neighbor interface gigabitethernet 2/1/1', which is an interface that I know to be an inter-switch link, it returns 'Number of neighbors: 0'. Perhaps that's because that interface is part of a port channel?
I don't really need to know the OUI because the connected switch is also an Aruba switch. I'm just trying to confirm (for documentation purposes) which switchports on each device connect to which switchports on the upstream/downstream device.
