Ethernet Port-channel
Cisco ASR 903 router supports layer 2 and layer 3 port-channels, and only LACP is supported for link
aggregation. Here are the steps to create layer 3 port-channel.
interface Port-channel
ip address x.x.x.x y.y.y.y
interface GigabitEthernet0/0/1
no ip address
negotiation auto
channel-group channel-number mode active
For layer 2 port-channel, if there are EFPs or EFP trunk configured under port-channel, l2 protocol peering is
needed under port-channel to enable LACP.
interface port-channel 1
service instance 1 ethernet
encapsulation untagged
bridge-domain id
