Configuration result:
Add ports 1, 2, 3, 4 of S1 to port- group1 in order, and we can see a group in “on” mode is
completely j oined forcedly, switch in other ends won’t exchange LACP PDU to complete
aggregation. Aggregation finishes immediately when the command to add port 1/2 to port-
group 1 is entered, port 1 and port 2 aggregate to be port-channel 1, when port 1/3 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, when port 1/4 joins port-group 1, port-channel 1 of port 1, 2 and 3 are
ungrouped and re-aggregate with port 4 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 four ports in both S1 and S2 are aggregated in
“on” mode and become an aggregated port respectively.

If problems occur when configuring port aggregation, please first check the following for
causes.
