The protocol-group queue priority command configures the weight of the packets to be sent to the CPU in specific protocol queues.
The undo protocol-group queue priority command restores the default settings.
The default weight for protocol queues can be displayed by command display cpu-defend protocol-group queue configuration.

Usage Scenario
When congestion occurs in a protocol queue for packets to be sent to the CPU, packets with different priorities in the queue are scheduled based on their weights. Packets with larger weights are forwarded preferentially. When congestion occurs due to packet bursts, you can set the priority weight to allow packets with higher weights to preferentially pass.
