I'm trying to negotiate an etherchannel between a 3750G and a CIGESM in an IBM Blade Chassis. The CIGESM is currently setup with an etherchannel to a 3550 XL 12 port switch using copper gbics. However, I'm in the process of migrating these connections to the 3750G. It's a layer 2 etherchannel only in swithcport mode access "mode" only carrying VLAN 1 traffic. I've tried basically every config possible, but it just won't come up on the 3750G. I've tried channel-group xx mode on/passive/active/nonegotiate, etc. Even tried with dot1q trunking and no luck. On the 3550, it works just fine. There are 2 ports in the etherchannel, but I can't even get one working.
How is the bladecenter setup ? Just match the parameters on each side . There should no reason for it not to come up. Both ends of the link should match for the etherchannel . Shutdown the ports you are dealing and you should just be able to copy the parameters out of the bladecenter end and then bring both ports up at the same time . I always let it negotiate the channel using either pagp or lacp, though some people prefer to force them on . . Make sure the ports are switchports and not routed ports .
For LACP it is as simple as
channel-group x mode active --> same on both ends .
channel-group x mode desirable non-silent --> same on both ends.
The switches are normally managed thru the connection to the network management module of the bladecenter itself and does not ride the connection to the cisco bladeswitches so really vlan 2 is the only vlan needed to ride the switch connection.
