lacp vrrp priority

Function

The lacp vrrp priority command sets the LACP system priority of an Eth-Trunk interface when the Eth-Trunk interface works in static LACP mode and is associated with a VRRP group.

The undo lacp vrrp priority command restores the default system priority of an Eth-Trunk interface when the Eth-Trunk interface works in static LACP mode and is associated with a VRRP group.

By default, the configured LACP system priority of an Eth-Trunk interface in static LACP mode takes effect.

Usage Guidelines

Usage Scenario

A non-Huawei CE is dual-homed to Huawei UPE1 and UPE2. Eth-Trunk links in static LACP mode are configured between the CE and the UPEs. UPE1 and UPE2 are configured as a VRRP group, with UPE1 being Master and UPE2 being Backup. After an Eth-Trunk interface in static LACP mode is associated with a VRRP group, the Eth-Trunk link can rapidly detect the status change of the VRRP group. When detecting a status change of the VRRP group, the Eth-Trunk interface can rapidly switch traffic to an available link. This ensures reliable service transmission.

To allow the function of associating an Eth-Trunk interface in static mode with a VRRP group to take effect, run the lacp vrrp priority priority command to set the same LACP system priority on the UPE1 and UPE2 Eth-Trunk interfaces associated with the same VRRP group.

Prerequisites

The Eth-Trunk interface in static LACP mode has been associated with a VRRP group using the lacp track vrrp vrid vrid interface interface-type interface-number command.

Follow-up Procedure

When a non-Huawei device is dual-homed to two Huawei UPEs:

Run the lacp system-id mac-address command on the Eth-Trunk interfaces of the UPEs to set the same LACP system ID.
Run the lacp port-id-extension enable command to increase the number of each member interface in one of the Eth-Trunk interfaces by 32768.

Example

# Set the LACP system priority of the Eth-Trunk interface in static LACP mode to 1000.
