I've been trying to implement Link Aggregation on a Cisco 2611XM Router, using the onboard interfaces FastEthernet0/0 and FastEthernet0/1, so far I followed this article:
Simple said, I want to create a trunk with the two Fast Ethernet interfaces onboard.
In the global configuration mode I've identified the port channel and tried to configure the interface in a channel group:
Enter configuration commands, one per line. End with CNTL/Z.
arnsberg(config)#interface port-channel 1
arnsberg(config-if)#channel-group 5 mode active
% Invalid input detected at '^' marker.
As you can see, the channel-group command is unrecognized. I am running IOS 12.3(4)T7.
Is IEEE 802.3ab not supported in the Type T Release?
