LACP between 3750 and Enterasys C2

Hello, has anyone successfully

usedlacp to connect to an Enterasys C2 (or A2 for that matter) switch? The connection works from the 3650 to a 3550. The Enterasys lag works from the C2 to an A2 but when I try to connect the 3750 to the C2 the port-channel won't come up.

Just an update if someone else is stuck, I changed the C2 to remove any

reference to static ports and the link comes up. Don't know why. Hopefully someone at Enterasys can provide an idea..

Thanks to those that looked.
