Priority Commands

Priority Commands

The commands described in this section allow you to specify which data packets have greater precedence when traffic is buffered in the switch due to congestion. This switch supports CoS with four priority queues for each port. Data packets in a port’s high-priority queue will be transmitted before those in the lower-priority queues. You can set the default priority for each interface, the relative weight of each queue, and the mapping of frame priority tags to the switch’s priority queues.

Command Groups	Function	Page
Priority (Layer 2)	Configures default priority for untagged frames, sets queue weights,	4-147
	and maps class of service tags to hardware queues
Priority (Layer 3 and 4)	Maps TCP ports, IP precedence tags, or IP DSCP tags to class of	4-152
	service values

switchport priority default

This command sets a priority for incoming untagged frames. Use the no form to restore the default value.

Syntax

switchport priority default default-priority-idno switchport priority default

default-priority-id- The priority number for untagged ingress traffic. The priority is a number from 0 to 7. Seven is the highest priority.

Default Setting

The priority is not set, and the default value for untagged frames received on the interface is zero.

4-147

VS4512DC, VS4512 specifications

Accton Technology is renowned for its innovative networking solutions and has made significant strides in the realm of networking devices with its VS4512 and VS4512DC models.
