Hello.
I have router Cisco 3945 with switching module EHWIC-4ESG, IOS version c3900-universalk9-mz.SPA.153-1.T.bin
The problem is that I cannot including switching interfaces (gi0/0/0 - 0/0/3) in created channel-group, that is no command "channel-group" in
"(config-if)# " on switching interfaces:
(config-if)#channel-group
^
% Invalid input detected at '^' marker.
What's wrong?
