Link Layer Discovery Protocol (LLDP / LLDP-MED) -------------- I guess a hint that some port is more than an ordinary port, would be the fact that it has more than one mac-address assigned on the forwarding database to that port. That of course wouldn't say much as to what is on the other side of the cable --jp Em 23-04-2010 14:40, Vidar Faltinsen escreveu:

Another question: is there any way to detect switch candidates analysing NAV's database? I'm trying to configure all switches into NAV, but there are many and the lists I have may be incomplete. Another reason to do this analysis regularly might be to detect "rogue" switches connected onto the network
You can find (CDP enabled) switches (and phones...) not added to NAV by looking at the predefined "Unrecognized CDP neighbours" under Reports :-)
Yes and somewhere down the road (say NAV 3.7) we should get LLDP [1] support and then all LLDP capable neighbours can be detected as well. That should help even more :) Does 3com support LLDP?
