Queue Mode - SMC Networks SMC8624/48T Management Manual

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, 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.
Console(config)#queue mode strict
