Actually, the 'pub...@643' community he has there gives the table for VLAN 643.
And I've seen that sort of thing before, and it seems to be random (there's probably some rhyme or reason, but I've learned that if I get the table via SNMP multiple times, at different times of day, it eventually catches it all).

Because you're polling the wrong oid? ipNetToMedia is the arp table. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
