7.4 Link Aggregation Configuration Example

I. Network requirements
Switch A connects switch B with three aggregation ports, numbered as Ethernet2/1/1 to
Ethernet2/1/3, so that incoming/outgoing load can be balanced among the member
ports.

III. Configuration procedure
The following only lists the configuration for switch A, and that on switch B is similar.
1) In manual aggregation mode
Create aggregation group 1.
[SW8800] link-aggregation group 1 mode manual
Add Ethernet ports Ethernet2/1/1 to Ethernet2/1/3 into aggregation group 1.
[SW8800] interface ethernet2/1/1
[SW8800-Ethernet2/1/1] port link-aggregation group 1
[SW8800-Ethernet2/1/1] interface ethernet2/1/2
[SW8800-Ethernet2/1/2] port link-aggregation group 1
[SW8800-Ethernet2/1/2] interface ethernet2/1/3
[SW8800-Ethernet2/1/3] port link-aggregation group 1
2) In static LACP aggregation mode
Create aggregation group 1.
[SW8800] link-aggregation group 1 mode static
Add Ethernet ports Ethernet2/1/1 to Ethernet2/1/3 into aggregation group 1.
[SW8800] interface ethernet2/1/1
[SW8800-Ethernet2/1/1] port link-aggregation group 1
[SW8800-Ethernet2/1/1] interface ethernet2/1/2
[SW8800-Ethernet2/1/2] port link-aggregation group 1
[SW8800-Ethernet2/1/2] interface ethernet2/1/3
[SW8800-Ethernet2/1/3] port link-aggregation group 1
3) In dynamic LACP aggregation mode
