I'm having quite a bit of trouble getting an EtherChannel (just layer-2 would be fine) configured between a Catalyst 4006 (running CatOS8.1(2)) and a 4-port Cisco switch module (running IOS 12.1(22)) that's part of an IBM BladeCenter. The Catalyst has all of its modules set to PAgP, which I would prefer to use over LACP. I am not actually sure how to check what channel protocols are set on the BladeCenter's switch, though.
On the Catalyst, I would like to use ports 4/20 and 4/21 to make a dual-gigabit EtherChannel to the Cisco. Therefore, on the Catalyst, I have this enabled:
set port channel 4/20-21 mode on
I'm rather a little bit lost when it comes to setting up the switch running IOS, though. I found this command in some Cisco docs:
channel-group 1 mode on
(applied to the relevant interfaces), but I'm not sure if this is all that I need. Could anyone please point me in the correct direction with what else I need to do to get everything running?
