Figure 11 Set the aggregation state of a member port in a static aggregation group
To ensure stable aggregation state and service continuity, do not change port attributes or class-two
configurations on any member port.
If a static aggregation group has reached the limit on selected ports, any port joins the group is placed in
the unselected state to avoid traffic interruption on the current selected ports. Avoid this situation, however,
because it may cause the aggregation state of a port to change after a reboot.
Aggregating links in dynamic mode
LACP is enabled automatically on all member ports in a dynamic aggregation group. The protocol
automatically maintains the aggregation state of ports.
The dynamic link aggregation procedure comprises:
• Selecting a reference port
• Setting the aggregation state of each member port
Selecting a reference port
The local system (the actor) and the remote system (the partner) negotiate a reference port using the
following workflow:
