lacp system-id
Function
The lacp system-id command configures a Link Aggregation Control Protocol (LACP) system ID for an Eth-Trunk.
The undo lacp system-id command restores the default configuration.
By default, the system bridge MAC address functions as the LACP system ID of an Eth-Trunk.
Only the S5720-EI, S5720-HI, S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
Parameters
| Parameter | Description | Value |
|---|---|---|
| mac-address | Specifies the LACP system ID of an Eth-Trunk. |
The value is in the format of H-H-H. Each H is a 4-digit
hexadecimal number. You can enter 1 to 4 digits, such as 00e0 or fc01.
If an H contains fewer than four digits, 0s are added ahead. For example,
e0 is equal to 00e0. NOTE:
The LACP system ID of an Eth-Trunk
cannot be all 0s. |
Usage Guidelines
Usage Scenario
When multiple E-Trunks are configured on the device, the link aggregation groups can use different LACP system IDs. You need to run the lacp system-id mac-address command to set the LACP system ID.
The LACP system ID configured using the lacp e-trunk system-id command in the system view is valid for all Eth-Trunks that are added to the E-Trunk. The LACP system ID configured using the lacp system-id mac-address command in the Eth-Trunk interface view is valid for only the Eth-Trunk. If the LACP system ID is configured in both the Eth-Trunk interface view and system view, the system ID configured in the Eth-Trunk interface view takes effect.
Prerequisites
The Eth-Trunk has been configured to work in LACP mode using the mode lacp command.
