Usage Guidelines

Usage Scenario

LACP system priorities or IDs determine which Eth-Trunk interface in static LACP mode at either end of an Eth-Trunk link can function as the Actor.

The two Eth-Trunk interfaces first compare their LACP system priorities. The one with a smaller LACP system priority is selected as the Actor.
The default LACP system priority is 32768. It can be changed using the lacp priority command.
If the two Eth-Trunk interfaces have the same LACP system priority, they compare their system IDs. The one with a smaller system ID is selected as the Actor.
The default LACP system ID is the MAC address of an main control board's Ethernet interface.
The display eth-trunk command can be used to check the LACP system priority and system ID only after an Eth-Trunk interface working in static LACP mode is configured, causing inconvenience in network planning. To facilitate network planning, you can run the display lacp brief command to check the LACP system priority and system ID when no Eth-Trunk interface working in static LACP mode is configured.

Example

The actual command output varies according to the device. The command output here is only an example.

# Add an Eth-Trunk interface in LACP mode to an E-Trunk and enable system ID synchronization with the peer end. Then, display brief LACP information.

<DEVICE> display lacp brief
System Priority: 32768
System ID      : 00e0-fc12-3456
--------------------------------------------------------------------------------
Eth-Trunk1:
System Priority: 32768
System ID      : 00e0-fc12-3458(Remote)

# Display brief LACP information.

<DEVICE> display lacp brief
System Priority:32768
System ID      :00e0-fc12-3457

**Table 1** Description of the **display lacp brief** command output
Item	Description
System Priority	LACP system priority, which can be changed using the lacp priority command.
System ID	LACP system ID, which is fixed at the MAC address of an Ethernet interface on the device's main control board.
Eth-Trunk1	Eth-Trunk ID.
Remote	Interface's system ID synchronized with that on the peer device through an E-Trunk connection.
