Setting the aggregation state of each member port
Selecting a reference port
The system selects a reference port from the member ports that are in up state and have the same
class-two configurations as the aggregate interface.
The candidate ports are sorted by aggregation priority, duplex, and speed in this order: lowest
aggregation priority value, full duplex/high speed, full duplex/low speed, half duplex/high speed, and
half duplex/low speed. 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 11 Setting 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 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.
