Parameters
- traffic-class-queues
- Specifies the traffic class strict priority queues. Enter one of the following integers:
- 0—No strict priority queues
- 1—Traffic class 7 strict priority queue
- 2—Traffic class 6 through 7 strict priority queues
- 3—Traffic class 5 through 7 strict priority queues
- 4—Traffic class 4 through 7 strict priority queues
- 5—Traffic class 3 through 7 strict priority queues
- 6—Traffic class 2 through 7 strict priority queues
- 7—Traffic class 1 through 7 strict priority queues

TC6-BW%
TC7-BW%
- Configures the Deficit Weighted Round Robin queues in percentage for each traffic class, if the priority is in weighted fair queue (WFQ) mode. Enter an integer from 0 through 100 (TC0-BW for traffic class 0 through
TC7-BW for traffic class 7). The total of all values must equal 100%.
-
TC0 - TC7
bytes
-
Sets the maximum bandwidth the queue can transmit. This value is in bytes.
Modes
Policy-map configuration mode
Usage Guidelines
This command is allowed only for the egress direction.
Use the
no form of this command to remove QoS egress scheduling from the interface.
Examples
The following example configures QoS egress scheduling on an interface.
device# configure terminal
device(config)# policy-map policy_1
device(config-policymap)# class default
device(config-policymap-class)# scheduler strict-priority 1 dwrr 25 25 25 10 5 5 5
The following example command configures the QoS egress scheduling on an interface with TC0-TC3
with equal weights and TC4-TC7 as strict, but with queue shapers of 2.0 Gbps, 1.5 Gbps, 1.0 Gbps,
and 0.5 Gbps respectively.
device# configure terminal
device(config)# policy-map policy_2
device(config-policymap)#class default
device(config-policymap-class)# scheduler strict-priority 4 dwrr 25 25 25 25
TC4 2000000 TC5 1500000 TC6 1000000 TC7 500000
device(config-policymap-class)# int eth 0/29-30
device(conf-if-eth-0/29-30)# no service-policy out
device(conf-if-eth-0/29-30)# service-policy out h1
