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.

Priority Commands (Layer 2)

Configures default priority for untagged frames, sets queue weights, and maps class of service tags to hardware queues

Priority Commands (Layer 2)

Command	Function
queue mode	Syntax:
This command sets the	queue mode {strict wrr}
queue mode to strict	no queue mode
	• strict - Services the egress queues in sequential order, transmitting all traffic in
priority or Weighted
	the higher priority queues before servicing lower priority queues.
Round-Robin (WRR) for
	• wrr - Weighted Round-Robin shares bandwidth at the egress ports by using
the class of service (CoS)
priority queues.	scheduling weights 1, 2, 4, 6 for queues 0 - 3 respectively.
Use the no form to restore	Default Setting: Weighted Round Robin
the default value.	Command Mode: Global Configuration
	Command Usage: You can set the switch to service the queues based on a strict
	rule that requires all traffic in a higher priority queue to be processed before lower
	priority queues are serviced, or use Weighted Round-Robin (WRR) queuing that
	specifies a relative weight of each queue. WRR uses a predefined relative weight
	for each queue that determines the percentage of service time the switch services
	each queue before moving on to the next queue. This prevents the head-of-line
	blocking that can occur with strict priority queuing.
	Example: The following example sets the queue mode to strict priority service
	mode:
	Console(config)#queue mode strict
	Console(config)#
show queue mode	Default Setting: None
This command shows the	Command Mode: Privileged Exec
current queue mode.	Example:
	Console#show queue mode
	Queue mode: wrr
