Usage Guidelines

Usage Scenario

Devices at both ends of an Eth-Trunk compare LACP system priorities and system IDs to determine the Actor during LACP negotiation.

By default, the LACP system priority is 32768, and the device with the smaller LACP system ID is used as the Actor.
If LACP system priorities are changed using the lacp priority command, the device with the smaller LACP system priority is used as the Actor.

The display eth-trunk command can be used to check the LACP system priority and system ID only after an Eth-Trunk in LACP mode has been configured. This is inconvenient for 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 in LACP mode is configured.

Precautions

When two PEs join an E-Trunk, run the lacp e-trunk system-id command on the PEs to configure the same E-Trunk LACP system ID so that the CE considers the PEs to be one device. The E-Trunk LACP system ID configurations do not affect LACP system IDs of Eth-Trunks in LACP mode. The LACP system ID of an Eth-Trunk in LACP mode is the MAC address of the Ethernet interface on the device.

E-Trunk is supported by only the following models: S5720-EI, S5720-HI, S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730-HI, S5730S-EI, S5730-SI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720-LI, S6720S-EI, S6720S-LI, S6720S-SI, S6720-SI, S6730-H, S6730S-H, S6730-S, and S6730S-S.
