I had try to trunk a Cisco 3750 with Avaya P133G2 and until now I don’t have any idea what is the right way to do so.The configuration for the cisco switch as per below:
Switchport mode trunk dynamic desirable.
At the Avaya swith I had configured the trunk mode also at the Gigabit port.
Do I miss anything since I had tested the connection but it still not working?
Somebody please help me.
