I am using indeed 7.6R1.9 . I wasn't aware of this bug. Thanks! By redoing it again, I managed to activate the trunk by forcing "channel-group 1 mode on" on both 3750 interfaces, putting the M320 in LACP passive mode and forcing all ports in a "no negociation" mode (they were already in this state before).
As far as I have understood, in this mode, LACP is not activated on Cisco side. CBV1SC(config-if)#channel-group 1 mode ? active Enable LACP unconditionally auto Enable PAgP only if a PAgP device is detected desirable Enable PAgP unconditionally on Enable Etherchannel only <---- HERE passive Enable LACP only if a LACP device is detected What does LACP bring more when it is working compared to this "Etherchannel only" mode ? Is it less reliable to leave it in this state without LACP activated ? For Vijay, I think that in my case , the M320 and the 3750 are negotiating themselves which actor and partner key.

If you are on 7.6-8.1 then you are effected with PR95015. LACP did not used always the correct interface index .32767 once you have received it. If you deactivate/activate the ge-4/1/4 and ge-4/1/5 then you should get the aggregate into up state. thanks Josef Wednesday, February 21, 2007, 11:02:17 AM, you wrote: IA> IA> IA> Hello, IA> IA> I have been reading some past discussions in this mailing IA> and trying things suggested in these discussions but I am not IA> able to setup a LACP link between a Cisco switch and a M320.
