The one at the top is selected as the reference port. If two ports have the same aggregation priority,
duplex mode, and speed, the one with the lower port number wins out.
Setting the aggregation state of each member port
After selecting the reference port, the static aggregation group sets the aggregation state of each
member port, as shown in Figure 5 .
Figure 5 Set the aggregation state of a member port in a static aggregation group
NOTE:
•
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 automatically enabled on all member ports in a dynamic aggregation group. The protocol
automatically maintains the aggregation state of ports.
The dynamic link aggregation process comprises:
• Selecting a reference port
• Setting the aggregation state of each member port
