(Optional) Setting the LACP Interface Priority
(Optional) Setting the LACP Interface Priority
Context
In LACP mode, LACP interface priorities are set to prioritize interfaces of the same device. Interfaces with higher priorities are selected as active interfaces.
Procedure
Run:
system-view
The system view is displayed.
Run:
interfaceinterface-typeinterface-number
The member interface view is displayed.
Run:
lacp prioritypriority
The LACP priority of the member interface is configured.
By default, the LACP interface
priority is 32768. A smaller priority value indicates a higher LACP priority.
By default, the system selects active interfaces based on interface priorities. However, low-speed member interfaces with high priorities may be selected as active
interfaces. To select high-speed member interfaces as active interfaces, run the lacp selected { priority | speed } command to configure the system to select active interfaces based on the interface rate.
If the max active-linknumberlink-number command is run in the Eth-Trunk interface view, you need to run the lacp preempt enable command to enable LACP preemption on the current Eth-Trunk
interface. Otherwise, interfaces with high LACP priorities may fail to be selected as active interfaces.
