Configuration result:
Add port 1, 2, 3 of Switch1 to port-group1 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 command adding port 2 to
port-group1 is entered, port 1 and port 2 aggregates to be port-channel1, when port 3
joins port-group1, port-channel1 of port 1 and 2 are ungrouped and re-aggregate with port
3 to form port-channel1. (it should be noted that whenever a new port joins in an
aggregated port group, the group will be ungrouped first and re-aggregate to form a new
group. Now all three ports in both Switch1 and Switch2 are aggregated in “on” mode and
become an aggregated port respectively.
