I understand the SUP active/standby, but the ports on the standby SUP are capable of being up and route traffic.
I will take a look into using a VLAN or the "backup interface" route.

There may be a misconception underlying this desire. "Both" SUPs are not active/available for use. The 2nd SUP is in either cold or hot standby mode, depending on your redundancy config. Conceptually, the device has a single active forwarding engine - and you can't have overlapping IPs, so basically this won't work. > One SUP to one 3560 and the other to the second 3560.

Just use a VLAN interface; if the SUP fails over, the 2nd SUP will take it on: inteface VlanX ip address 1.1.1.1 255.255.255.0 int Gi1/1 description 3560-1 switchport switchport mode access switchport access vlan X int Gi1/2 description 3560-2 switchport switchport mode access switchport access vlan X You will need spanning tree to close the layer2 loop. There are other ways to do this - the "backup interface" stuff just today discussed on the list for example. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
