LACP SUSPENDED STATE

Hi,
i have configured a multicassis etherchannel between some catalyst 2960x and two C9500-x configured in stackwise virtual. I''m encountering this issue, when i boot all the stackwise at the same time the LAG work proprely, but if the only standby member reload  when it completed the boot the remote switch 2960x place the connected port in suspended mode and the switch stop propagate traffic on all bundle port. I have the same issue whit LACP, PAGP or static mode.
Any ideas?
Thanks

Re: LACP SUSPENDED STATE

Can you post the configuration of both the switches to verify.

Dear e.rapaccioli,
1. Your configurations are ok.
2. interfaces's speed's on 9500-X are 10Gb and on 2960X are 1Gb. I dont know if they are in auto negociate state.

 

Try setting on 9500-X are 10Gb

interface TenGigabitEthernet1/0/1

speed 1000

interface TenGigabitEthernet2/0/1

speed 1000
