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:

Sorry, what I meant is that the Avaya seems not to be understanding the LACP from cisco side.
I would try mode "on" just to make sure

The port channel is SD' meaning it down?
In SW you need to do these step in these seq
1- make port member of PO
2- config PO
3- no shut PO
07-22-2023 11:27 AM
Please @MHM Cisco World what does PO stand for?
07-22-2023 11:30 AM
PO Port channel
07-22-2023 11:26 AM
If you connect both switches only with one interface the interfaces come up correctly?
If yes, configure the port-channel with the "on" and "passive" mode. Just to make sure the mode is not wrong considering the Avaya side.
channel-group number mode {active | on | passive}
07-22-2023 11:30 AM
@Flavio Miranda I connected the two switches with only one port but the port-channel always remains in "suspended" mode
07-22-2023 11:47 AM
But without port-channel the interface stay UP ? Just trying to make sure you dont have a problem on the basic which is interface.
07-22-2023 12:04 PM
yes without the PO port 24 is UP when we connect the cable as you can see on the outputs of the command "show interfaces twentyFiveGigE 1/0/24" that I shared above
07-22-2023 11:40 AM
@Flavio Miranda @MHM Cisco World
you can see the lacp config on the avaya switch in the attached file
07-22-2023 11:43 AM
@Flavio Miranda @MHM Cisco World
LACP and TRUNK on avaya switch
07-22-2023 12:04 PM
@arouna.kikone1 the configuration seems to be ok but I would like to confirm with you are able to get the interface up without the port channel config.
07-22-2023 12:07 PM
@Flavio Miranda yes without the PO port 24 is UP when we connect the cable as you can see on the outputs of the command "show interfaces twentyFiveGigE 1/0/24" that I shared above
07-22-2023 12:12 PM
One port the PO is up add other one the PO is down'
Try
PO shut
connect cable to both port
PO no shut
The PO is down because of stp issue

@MHM Cisco World we are at the weekend of here work resumes on Monday.
I'll check the track you put me on and get back to you.

Yes' also share show lacp internal when you back to site.
