Aggregating Links in Static Mode
LACP is disabled on the member ports in a static aggregation group. The aggregation state of the
member ports must be maintained manually.
Static link aggregation comprises:
z Selecting a reference port
z 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 the up state and have the same
class-two configurations as the aggregate interface.
The candidate ports are sorted by duplex and speed in this order: 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 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 1-2 .
