Switch2 (Config)#interface eth 1/6

Switch2 (Config-Ethernet1/6)#port-group 2 mode on

Switch2 (Config-Ethernet1/6)#exit

Switch2 (Config)# interface eth 1/8-9

Switch2 (Config-Port-Range)#port-group 2 mode on

Switch2 (Config-Port-Range)#exit

Configuration result:

Add ports 1, 2, 3 of Switch 1 to port-group 1 in order, and we can see joining a group in “on” mode is completely forced action, switch in other ends won’t exchange LACP PDU to complete aggregation. Aggregation finishes immediately when the command to add port 2 to port-group 1 is entered, port 1 and port 2 aggregate to be port-channel 1, when port 3 joins port-group 1, port-channel 1 of port 1 and 2 are ungrouped and re-aggregate with port 3 to form port-channel 1. (it should be noted that whenever a new port joins in an aggregated port group, the group will be ungrouped first and re-aggregated to form a new group. Now all three ports in both Switch 1 and Switch 2 are aggregated in “on” mode and become an aggregated port respectively.
