• 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, 6, 8, 10, 12, 14 for queues 0 - 7
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.
