Link Aggregation between ProCurve and Comware Switches

Suppose we want to do link aggregation between ports A1-A2 on the ProCurve 5400 side and ports GigabitEthernet 1/0/1 and 1/0/2 on the Comware 5900 side, with all VLANs permitted  and VLAN 100 as the untagged VLAN on the aggregated link. We can configure a static non-protocol link aggregation or a static LACP link aggregation as described below:

1. Configuring a static, non-protocol link aggregation:

On the 5900 Comware side, enter the following commands in system view mode:

interface bridge-aggregation 1
port link-type trunk
port trunk permit vlan all
port trunk pvid vlan 100
quit

interface gigabitethernet 1/0/1
port link-aggregation group 1
quit

interface gigabitethernet 1/0/2
port link-aggregation group 1
quit


On the ProCurve 5400 side, enter the following command in configuration mode:

trunk a1-a2 trk1 trunk

Also the interface trk1 must be untagged for VLAN 100 and tagged for all other VLANs.

For verification, issue the command display link-aggregation verbose in the Comware switch and show trunk in the ProCurve switch.

2. Configuring a static LACP link aggregation:

On the 5900 Comware side, enter the following commands in system view mode:

interface bridge-aggregation 1
port link-type trunk
port trunk permit vlan all
port trunk pvid vlan 100
link-aggregation mode dynamic
quit

interface gigabitethernet 1/0/1
port link-aggregation group 1
quit

interface gigabitethernet 1/0/2
port link-aggregation group 1
quit


On the ProCurve 5400 side, enter the following command in configuration mode:

trunk a1-a2 trk1 lacp

Also the interface trk1 must be untagged for VLAN 100 and tagged for all other VLANs.

For verification, issue the command display link-aggregation verbose in the Comware switch and show lacp in the ProCurve switch.
