Yes, there is.
R5 is connected to 3550-2 F0/5
R4 is connected to 3550-2 F0/4
It seems that I had them both on the same vlan! I guess that would be what
caused the problem, but what exactly was happening?
On another note, is there a way to reset DLSW peers? I know there isn't a
command to 'clear dlsw peer' but how doe I reset the stats/peers from 'sh
dlsw peer'?
r4#sh dlsw peer
Peers: state pkts_rx pkts_tx type drops ckts TCP

Hi Jason,
Sounds like a spanning tree broadcast storm problem. Do you have a switch
somewhere in the mix?
