Each port in the HP 1:10GbE switch can have one of the following LACP modes.
off (default)—The user can configure this port in to a regular static trunk group.
active—The port is capable of forming an LACP trunk. This port sends LACPDU packets to partner
system ports.
passive—The port is capable of forming an LACP trunk. This port only responds to the LACPDU
packets sent from an LACP active port.
Each active LACP port transmits LACP data units (LACPDUs), while each passive LACP port listens for
LACPDUs. During LACP negotiation, the admin key is exchanged. The LACP trunk group is enabled as
long as the information matches at both ends of the link. If the admin key value changes for a port at
either end of the link, that port's association with the LACP trunk group is lost.
When the system is initialized, all ports by default are in LACP off mode and are assigned unique admin
keys. To make a group of ports aggregatable, you assign them all the same admin key. You must set the
port's LACP mode to active to activate LACP negotiation. You can set other port's LACP mode to passive,
to reduce the amount of LACPDU traffic at the initial trunk-forming stage.
Use the /info/l2/trunk command or the /info/l2/lacp/dump command to check whether the
ports are trunked.
NOTE:
If you configure LACP on ports with 802.1x network access control, make sure the ports on
both sides of the connection are properly configured for both LACP and 802.1x.

Configuring LACP

Use the following procedure to configure LACP for port 22 and port 23 to participate in link aggregation.
1.
Set the LACP mode on port 20.
>> # /cfg/l2/lacp/port 22
>> LACP port 22# mode active
2.
Define the admin key on port 22. Only ports with the same admin key can form a LACP trunk group.
>> LACP port 22# adminkey 100
Current LACP port adminkey:
New pending LACP port adminkey: 100
3.
Set the LACP mode on port 23.
>> # /cfg/l2/lacp/port 23
>> LACP port 21# mode active
4.
Define the admin key on port 23.
>> LACP port 23# adminkey 100
Current LACP port adminkey:
New pending LACP port adminkey: 100
5.
Apply and verify the configuration.
>> LACP port 23# apply
>> LACP port 23# cur
6.
Save your new configuration changes.
>> LACP port 23# save
