Hi, I have Catalyst 3560 and 2960 switches connected by a two member Etherchannel trunk using built in copper GE interfaces. For some reason Ethernet autonegotiation ends up assigning unmatching speeds for one link (10M in one switch, 100M in other) and the interfaces end up in suspended state.
MGMT-14#show int status | inc 35|36 Gi0/35 connected trunk a-full a-1000 10/100/1000BaseTX Gi0/36 suspended trunk a-full a-100 10/100/1000BaseTX MGMT-13#show int status | inc 23|24 Gi0/23 connected trunk a-full a-1000 10/100/1000BaseTX Gi0/24 suspended trunk a-full a-10 10/100/1000BaseTX Any ideas what might be causing this. I wonder if I'm running into some kind of minimum cable length problem. Switches are sitting adjacent to each other in a rack and connected with very short cables (0.5m ~ 2 ft). -Juuso Lehtinen _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
