CanogaOS Command Reference

4. Queues in the same class will be served by WDRR (Weight Deficit Round Robin) scheduling

algorithm. And, queues in different classes will be served by SP (Strictly Priority) scheduling

algorithm.

Examples

In the following example, the queue-rate command is used to configure queue shaping rates for queue

1 to queue 3 of a EVC at egress NNI direction.

Switch(config)# qos net-egress evc110-policy-at-egress-nni

Switch(config-net-egress)# queue-rate 8000 4000 2000

32.11 queue-weight

Use this command to configure a bandwidth allocation weight for queue 0 in network egress policy. To

use the default weight, use the no form of this command. The default weight of queue 0 is 1.

Command Syntax

queue-weight WEIGHT

no queue-weight

WEIGHT: The weight value of queue 0 of all EVCs at egress NNI accounts for proportional bandwidth

sharing. The valid weight value ranges from 1 to 100.

Command Mode

Network Egress Policy Configuration

Usage

1. In network egress policy, the queue 1 - queue 3 are always treated with high priorities to be

scheduled and their bandwidths are generally committed through configuring the queue-rate. So, the

system does not allow to configure their weight values.

2. Queue 0 is generally used by BE (Best Effort) traffic, and it only use the residual bandwidth left by

high-priority queues. The weight values is used for WDRR scheduling in a same class.

Examples

In the following example, the queue-weight command is used to assign a weight for WDRR scheduling

for queue 0 in the network egress policy.

Switch(config)# qos net-egress evc110-policy-at-egress-nni

Switch(config-net-egress)# queue-weight 2
