Port Scheduler Policy Commands
port-scheduler-policy
Syntax no] port-scheduler-policy port-scheduler-name
[
Context config>qos
Description
The default scheduling done for a port is strict scheduling.When a port-scheduler policy is applied to
a port , it overrides the default scheduling and determines the type of scheduling (Strict, RR, WRR,
WDRR, WRR/WDRR + Strict) to be done between the 8 CoS queues of that particular port. When a
port scheduler policy is detached from a port, the port reverts back to the default scheduling (strict).
The no form of the command removes the policy from the system.
Parameters
port-scheduler-name — specifies an existing policy name. Each port-scheduler policy name should
mode
Syntax mode {strict | rr | wrr | wdrr}
no mode
Context config>qos>port-sched-plcy
Description
This command configures a particular mode of scheduling for the policy. For example, this implies
that when a policy with a mode RR is applied to a port then that port will follow the round robin type
of scheduling between its queues.
Parameters mode — Specifies the port scheduler policy mode.
queue
Syntax queue queue-id [strict |weight weight]
no queue queue-id
Context config>qos>port-sched-plcy
Description This command configures a port scheduler queue. The queue and its weights can be configured only
for WRR/WDRR modes. The weight specified in case of WRR corresponds to the number of packets
that needs to be sent out in a cycle for that particular queue.
For WDRR, the weight specified is the ratio of traffic that will be sent out for that particular queue.
For example, in WDRR, if a weight value for queue 1 is 1 and a weight value for queue 2 is 5, then

strict — Strict scheduler mode
rr — Round Robin
wrr — Weighted Round Robin
wdrr — Weighted Deficit Round Robin
