You specify which ports are part of a port-channel using the 'channel-group' command in the port context. qs1#self Enter configuration commands, one per line.  End with CNTL/Z. qs1(config-device-00-23-68-22-A3-DE)#interface ge 1 qs1(config-device-00-23-68-22-A3-DE-if-ge1)#channel-group 1 qs1(config-device-00-23-68-22-A3-DE-if-ge1)#exit qs1(config-device-00-23-68-22-A3-DE)#interface ge 2 qs1(config-device-00-23-68-22-A3-DE-if-ge2)#channel-group 1 qs1(config-device-00-23-68-22-A3-DE-if-ge2)#exit qs1(config-device-00-23-68-22-A3-DE)#interface port-channel 1 qs1(config-device-00-23-68-22-A3-DE-if-port-channel1)#

you then specify the settings for the port-channel under "interface port-channel 1". qs1(config-device-00-23-68-22-A3-DE)#interface port-channel 1 qs1(config-device-00-23-68-22-A3-DE-if-port-channel1)#switchport trunk allowed vlan 10,20
