How to set the LACP priority based on the rate


By default, the system selects active interfaces based on interface priorities. However, low-speed member interfaces may be selected as active interfaces because of their high priorities. To select high-speed member interfaces, run the lacp selected speed command to configure the system to select active interfaces based on the interface rate.

Assume that the AR router connects to users on private network segments of and and the rate limit needs to be set to 2 Mbit/s for each address in both inbound and outbound directions. Perform the following configurations: Enter the view of the public network interface.

Does an Eth-Trunk support LACP priority preemption
An Eth-Trunk supports LACP priority preemption only in LACP mode. You can run the lacp preempt enable command to enable LACP priority preemption. In LACP mode, when an active link fails, the system selects the link with the highest priority from backup links to replace the faulty one. After the faulty link recovers and the priority of the link is higher than that of the backup one, if LACP priority preemption is enabled, the link with a high priority replaces the link with a low priority and switches to active. LACP priority preemption configuration at both ends of an Eth-Trunk must be the same.

What is the default LACP system priority and election rule ?
LACP system priority is 32768, and the device with the smaller LACP system ID is used as the Actor.

How can I configure LACP priority on CE switches
LACP priorities include system and interface priorities. 1. The system priority determines the Actor and Partner. The device with a higher system priority functions as the Actor and the active interfaces are selected based on the Actor. 2. The interface priority determines selection of active interfaces. The interfaces with a higher priority are selected as active interfaces. A smaller value indicates a higher priority. # Configure the LACP system priority. system-view [~HUAWEI] lacp priority 10 [*HUAWEI] commit# # Configure the LACP priority for 10GE1/0/1. system-view [~HUAWEI] interface eth-trunk 1 [*HUAWEI-Eth-Trunk1] trunkport 10ge 1/0/1 [*HUAWEI-Eth-Trunk1] mode lacp-static //Before configuring the interface priority, ensure that the interface has been added to an Eth-Trunk in LACP mode.
