Operation
Display the ID of the local device
Display link aggregation details of a specified
port or port range
Clear LACP statistics about a specified port or
port range
Network requirements
Switch A connects to Switch B with three ports Ethernet 2/0/1 to Ethernet
■
2/0/3. 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 Adopt the manual aggregation mode
# Create manual aggregation group 1.
<SW7750> system-view
System View: return to User View with Ctrl+Z
[SW7750] link-aggregation group 1 mode manual
# Add Ethernet 2/0/1 through Ethernet 2/0/3 to aggregation group 1.
[SW7750] interface ethernet2/0/1
[SW7750-Ethernet2/0/1] port link-aggregation group 1
[SW7750-Ethernet2/0/1] interface ethernet2/0/2
[SW7750-Ethernet2/0/2] port link-aggregation group 1
[SW7750-Ethernet2/0/2] interface ethernet2/0/3
[SW7750-Ethernet2/0/3] port link-aggregation group 1
2 Adopt the static LACP aggregation mode
