1.4 Link Aggregation Configuration Example

I. Network requirements

Switch A connects to Switch B with three ports (Ethernet 2/0/1 through 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.

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.

Adopt the manual aggregation mode

# Create manual aggregation group 1.

<H3C> system-view

System View: return to User View with Ctrl+Z

[H3C] link-aggregation group 1 mode manual

# Add Ethernet 2/0/1 through Ethernet 2/0/3 to aggregation group 1.

[H3C] interface ethernet2/0/1

[H3C-Ethernet2/0/1] port link-aggregation group 1

[H3C-Ethernet2/0/1] interface ethernet2/0/2

[H3C-Ethernet2/0/2] port link-aggregation group 1

[H3C-Ethernet2/0/2] interface ethernet2/0/3

[H3C-Ethernet2/0/3] port link-aggregation group 1

Adopt the static LACP aggregation mode

# Create static aggregation group 1.
