How do you configure LACP on Comware?
Link Aggregration Control Protocol (LACP) is used to combine multiple ethernet ports into a bundle. This bundle shows up as one port to spanning tree protocol (STP) allowing multiple connections to occur between switches without blocking. This protocol is also used to connect multiple server links to a switch to increase over all bandwidth between the devices.
Comware devices use the terms bridge and link aggregation to configure the feature. Procurve uses trunk, trk. Cisco uses ether and port channel.
The example abo
ve has two HP 5800’s connected over their 10G ports 27 and 28 with an HP 7500 Chassis acting as the root bridge for Common Instance Spanning Tree.

On HP switch 5800B, both links are in STP Alternate mode (blocking).

Configuring the 5800B port 10G 27 and 28 for LACP. The “link-aggregration mode dynamic” causes the bridge-aggregration to use LACP, otherwise the default is “static.” Further the load-sharing method is Layer 3 based.

Even after configuring the 10G ports, the trunking config is not applied. You have to configure all changes after adding the 10G ports to the bridge-agg. Further, the other side, 5800A, is not configured so things are out of sync.

The 5800A bridge aggregate 1 is now doing LACP and is sharing with 5800B. But, the layer 2 config is for access not trunk.
