Etherchannel trunking
I'm trying to trunk two ports from one 3550 switch to another 3550 and can't seem to get it to come up.
Here's the config and test results:
SWITCH A

Any help much appreciated.
One other thing, not all of the allowed vlans are on both sides yet. Would that matter at this point?
Thanks!

I caught the shutdown after I posted and fixed that but still no change.
The port channel is created on SW-A so I'm curious why you think it's not.

The reason is that there is nothing under:
Can you paste configuration of both devices and result from # show interface status.
If Port channels are configured on both devices it should work if devices are not err-disabled, or that you have different configuration on Po interfaces and physical interfaces.

You have problems with VLANs, a lot of duplicated IP addresses, So I guess this is not production device.
