I wanna configure LACP etherchannel between 4500X and 6807 Catalyst switches. But it does not work. The etherchannel is L2 and has 4 10G ports. BTW mode on works successfuly. But it's not desired. both switches are VSS pair. I upgraded both switches to Cisco suggested IOS-XE version but the problem didn't solved.
I tried all order of configuraion:
In both cases the 'sh etherc su' command show me suspended state.
Any idea might help.
Tnx in advance
Are these directly connected or interconnected via fibre risers?
Have you tried using statc PC or even PAGP instead of LACP
I do remember having the same issue myself in which the PC didn’t come up when using link aggregation negotiation, I did manage to fix but I cannot think how!
Would you be able to share the PC configuration for both the 6500/4500 PC please, maybe that would jog my memory?
Just one thing, have you manually stipulated the LACP protocol on the physical interfaces?
Can you share your present interface and port-channel configuration also the output from the following:
show etherchannel detail
show etherchannel load-balance
show etherchannel port-channel
show lacp neighbor
show lacp sys-id
