Exactly four hours after I increased the MAC aging time to 14400, the flooding stops. Before it was nearly 20kpps: core2#sh int g4/46 | i rate Queueing strategy: fifo 30 second input rate 0 bits/sec, 0 packets/sec 30 second output rate 70000 bits/sec, 84 packets/sec Still confused why it took that long to start properly learning. -- ~Randy _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
