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 following 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.
