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:

@MHM Cisco World I can to ping the devices that are connected behind the AVAYA switch but the PO state is still on "down" and "notconnected".
Won't that cause problems later?

@MHM Cisco World it's always the same!!!
this interface does not make it easy for us
07-24-2023 09:21 AM
Ok let me check in my lab.
07-24-2023 10:07 AM
it seems to me that it is the trunk on the port that works and not the lacp. (Operational Mode: trunk (suspended member of bundle Po40))
Can you confirm this through the below outputs of the command "show interfaces twentyFiveGigE 1/0/24 switchport"?

I already suspect that but need to check, PO must have MAC same as interface 1/0/24 but it not get mac.
just I need to check this point
07-25-2023 05:39 AM
HI @MHM Cisco World no news for my problem?
07-24-2023 08:43 AM
Yes I see' and it ok stand alone
But I see PO is down not up?
Can you confirm again PO up down ?
07-24-2023 08:48 AM
@MHM Cisco World I manage to ping the devices that are connected behind the AVAYA switch but the PO is still in "down" mode

@MHM Cisco World how can i change the timeout in LACP to be long not short ?

Mode ON is nightmare and make loop dont do that ever' we use ON only between SW and server.
The lacp key in avaya I think issue but not so sure I dont have info about avaya alot.
in avaya which vlan allow in trunk ? same vlan allow in cisco sw trunk.
