uni eth-trunk lacp timeout
Function
The uni eth-trunk lacp timeout command configures the LACP timeout time for an Eth-Trunk interface on an AS.
The undo uni eth-trunk lacp timeout command restores the default LACP timeout time of an Eth-Trunk interface on an AS.
By default, the LACP timeout time of an Eth-Trunk interface on an AS is 90 seconds.
This command can only be executed on a parent switch.
Format
uni eth-trunk trunk-id lacp timeout fast [ user-defined user-defined-timeout ]
undo uni eth-trunk trunk-id lacp timeout
Parameters
Parameter |
Description |
Value |
|---|---|---|
trunk-id |
Specifies an Eth-Trunk ID. |
The value must be an Eth-Trunk ID that has been created using the uni eth-trunk command. |
| fast | Sets the LACP timeout time of an Eth-Trunk interface to 3 seconds. In this situation, the interval at which the remote end sends LACP PDUs is 1 second. |
- |
| user-defined user-defined-timeout | Indicates the user-defined LACP timeout time of an Eth-Trunk interface. |
The value is an integer that ranges from 3 to 90, in seconds. |
Usage Guidelines
Usage Scenario
By default, if a member interface of the remote Eth-Trunk interface is faulty, it takes 90 seconds for the local Eth-Trunk interface to detect the remote member interface status change. This results in data traffic loss because the local interface continues to forward data traffic to the faulty remote member interface within 90 seconds. To enable the local interface to detect the remote member interface status change in a timely manner, run the uni eth-trunk lacp timeout command to reduce the LACP timeout time.
Prerequisites
The uni eth-trunk lacp timeout command can be configured only when the uni eth-trunk command has been configured to create an Eth-Trunk interface and set its working mode to LACP mode.
Precautions
The uni eth-trunk lacp timeout command is deleted when the undo uni eth-trunk command is configured to delete the Eth-Trunk interface.
