Link Aggregation Configuration Example
Network requirements
As shown in Figure 16-1 :
z
Switch A connects to Switch B with three ports GigabitEthernet 1/0/1 to GigabitEthernet 1/0/3. It is
required that incoming/outgoing load between the two switches can be shared among the three
ports.
z
Adopt three different aggregation modes to implement link aggregation on the three ports between
switch A and B.
