In our LACP Cisco Configuration example, we will use the G1/0/0 and the G2/0/0 ports to configure link aggregation. The basic configuration steps are below.



On RouterA

RouterA> enable
RouterA# configure terminal
RouterA (config)# interface port-channel 1
RouterA (config-if)# lacp max-bundle 2
RouterA (config-if)# ip address
RouterA (config-if)# interface g1/0/0
RouterA (config-if)# no ip address
RouterA (config-if)# channel-group 1 mode active
RouterA (config-if)# exit
RouterA (config)# interface g2/0/0
RouterA (config-if)# no ip address
RouterA (config-if)# channel-group 1 mode active
RouterA (config-if)# end
