6509 is running IOS ver 72033.advipservcesk9_wan_mz.122-33.SXH2a
3750 stack consists of one 3750g-24ts and one 3750-24p running ipbasek9-122.46(SE).
When each end configured for "channel-group n mode on" the 3750 ports go into err-disable. With each end configured for "channel-group n mode desirable" 3750 will fail because PAgP does not work across stack, etherchannel ports need to be on same switch.
Has anyone else seen this problem and what action was taken to overcome this problem?
Re: etherchannel problems between 6509 and 3750 stack
Setting the "channel-group n mode on" command works providing you set the channel-group on the 3750 stack first, then the 6500 core node. Otherwise for some reason the switch ports go into "err-disable" and the ports have to be shut/no shut and the port-channel definition deleted and then re-instated.
