Port Scheduler Policy Commands
port-scheduler-policy
Syntax [ no] port-scheduler-policy port-scheduler-name [create]
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 be
unique and can go upto 32 ASCII characters in length.
create- — This keyword is used to create a port scheduler policy.
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.
strict — Strict scheduler mode
rr — Round Robin
wrr — Weighted Round Robin
wdrr — Weighted Deficit Round Robin
