You can also execute the reset command in user view to clear statistics on LACP
ports.

Example
Network requirements
■ Switch A connects to Switch B with three ports GigabitEthernet1/0/1 to
GigabitEthernet1/0/3. It is required that incoming/outgoing load between the two
switch can be shared among the three ports.
■ Adopt three different aggregation modes to implement link aggregation on the
three ports between switch A and B.

Configuration procedure
The following only lists the configuration on Switch A; you must perform the similar
configuration on Switch B to implement link aggregation.
1 Adopting manual aggregation mode
a Create manual aggregation group 1.

b Add ports GigabitEthernet1/0/1 through GigabitEthernet1/0/3 to aggregation
group 1.
