Hi ALL
I have two Cisco 9300X-24Y-E stacked switches. I want to implement etherchannel between my cisco switches with an avaya switch.
After the configurations and the interconnection of the switches, the port-channel goes into "suspended" mode.
Note that the cisco 9300 switch does not allow me to type the command "Switchport trunk encapsulation dot1q".
Need your help to solve this problem which prevents me from evolving in my project.
below is the ports config in etherchannel:

did you change the timeout in avaya ?

@MHM Cisco World yes we changed avaya lacp timeout to long but on the cisco side, port 1/0/24 is still in "suspended" mode as shown below:

shut not shut the PO
hope this issue have happy ending
07-24-2023 07:30 AM
the port status still hasn't changed despite the "shut" and "no shut" commands.
Is it imperative to connect all the ports that are in channel-group 40?

@MHM Cisco World it's always the same! It's not at all easy.

wow!!!! I manage to ping the devices that are connected behind the AVAYA switch!!!!
yay

Without Mode ON (risky) with mode active and Ping success.
If Yes you are so welcome
Note:- keep in your mind what I mention about ON when you want to use it in feature.
Have a nice summer
