1.4 Link Aggregation Configuration Example

I. Network requirements
Switch A connects to Switch B with three ports Ethernet1/0/1 to Ethernet1/0/3. 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.

III. 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
# Create manual aggregation group 1.
<Quidway> system-view
[Quidway] link-aggregation group 1 mode manual
# Add Ethernet1/0/1 through Ethernet1/0/3 to aggregation group 1.
[Quidway] interface Ethernet1/0/1
[Quidway-Ethernet1/0/1] port link-aggregation group 1
[Quidway-Ethernet1/0/1] interface Ethernet1/0/2
[Quidway-Ethernet1/0/2] port link-aggregation group 1
[Quidway-Ethernet1/0/2] interface Ethernet1/0/3
[Quidway-Ethernet1/0/3] port link-aggregation group 1
2) Adopting static LACP aggregation mode
# Create static aggregation group 1.
<Quidway> system-view
[Quidway] link-aggregation group 1 mode static
# Add Ethernet1/0/1 through Ethernet1/0/3 to aggregation group 1.
[Quidway] interface Ethernet1/0/1
