Priority Commands

queue mode
This command sets the queue mode to strict priority or Weighted Round-Robin
(WRR) for the class of service (CoS) priority queues. Use the
no
form to restore the
default value.
Syntax
queue mode
{
strict
|
wrr
}
no
queue mode
•
strict
- Services the egress queues in sequential order, transmitting all
traffic in the higher priority queues before servicing lower priority queues.
•
wrr
- Weighted Round-Robin shares bandwidth at the egress ports by using
scheduling weights 1, 2, 4, 8 for queues 0 - 3 respectively.
Default Setting
Weighted Round Robin
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:
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-id
no 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.
