Ah the old show mac-address-table command. And how it fails me on some of my Nortel switches.
Of course the idea here is simple, using this command - get the MAC of the device plugged into a port. Then on the router look at the arp table for the MAC, and viola - you have the IP of the device on that port.
On a few of our Nortel 5520s and 4548s, the command shows only the MACs in the native vlan. On others, it works as designed. As a workaround, I can specify the VLAN ID and it works, however going through each vlan won't be fun, especially since knowing it is apparently not working as it should.
Any ideas why this is the case?
