Port Channel Config on CAT 4006 with SUP3 Module

[astanislaus]

I have never configured Port Channel on CAT 4006 using SUP3 module (WS-X4014) running Cisco IOS. But I presume it shouldn't be too different to CAT 6500 or so. But I request that someone check the sanity of my Port Channel Config (attached) and also point me to some good links on CCO explaining Por Channel on SUP3 - WS-X4014 module - used in CAT 4006.

Looks ok to me , though myself I let PAGP build the trunk with the desirable command . I also thought I read on CCO somewhere that is the preferred way also but everyone does it there own way .

Should it be mode desirable at both ends OR

Mode "desirable" at one end AND

Mode "on" at the other end.

Check your VLANs allowed range on the physical interfaces. One switch is configured with 1-223 while the other is configured with 1-224. I believe the allowed VLANs must match.
