Guys, Im having a problem with a port-channel in a 4506.
I created 2 4-port etherchannels (int port-channel1 and int port-channel2) and all is well. Each of these 2 channels go to 2 Nortel Switches.
When I try to create a third 4-port etherchannel to a third Nortel switch, in theory I was expecting this to be smooth because they all the same, however this 3rd channel will not come up.
I checked the logs in the nortel switch and all clear. However, the logs in the 4506 have these messages:
EC-5-CANNOT_BUNDLE2: Gi4/14 is not compatible with Po3 and will be suspended (trunk mode of Gi4/14 is dynamic, Po3 is trunk)
I've changed ports in the 4506 (from 3/21-24 to 4/11-14) and the exact problems.
Can you guys please help?
thanks in advance
