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
