Hi

 Verify Te1/1 as per the logs: "Either port is L2 and port-channel is L3, or vice-versa"

We know that the Port-channel is L2 as per the commands you used "switchport" The other possibility is one of this port to be in L3.

You can do :

!

int range  Te1/1 - 2

switchport

!

Hello,

looking at the exact error message, it complains that Te1/1 is layer 3. Try the below:

core-utex2-1(config)# interface range te1/1 - 2
core-utex2-1(config-if-range)#switchport
core-utex2-1(config-if-range)#channel-group 20 mode on
