I just got a hold of a new C1111 router, and I was just wondering is there a particular reason that you can only put routed interfaces (Gi0/0/0 and Gi0/0/1) as members of port-channel or am I doing something wrong here ??? If that's the only option, I guess the idea behind this is just to create redundancy or increase bandwidth on an UPLINK. I would like to create port-channel towards my LAN network, but there is no option to put channel-group command on switched interfaces (Gi0/1/0 - Gi0/1/3).
I think that you might be right and that might indeed be the reason, however that said, Port-channels are used for other things than just increasing traffic flow.
I think its a sad thing that Cisco does not recognize the value of this feature for the edge routers.
The Cisco 1111-4p has 2 Routing ports and a 4 port switch.
That means I can get several different options for redundancies on the external interfaces.
I would love to have the possibility to connect a Port-channel to a switch/switch stack/VPC/2nd router to get link redundancy on the inside too. (Yes spanning tree is one option, but not the one i prefer!)
The most irritating part is that the command is half there, you can do the port-channel command but you can not add the number.
The ISR4221 has the identical problem when you add a 4 port switch module to it.
If anyone at Cisco is seeing this please consider adding this properly to the switch modules, it would help a lot with fault tolerance designs.
