Syntax sched-run-min-int percent-of-default
no sched-run-min-int
Context config>card>virt-sched-adj
Description
This command is used to override the default minimum time that must elapse before a virtual scheduler may
redistribute bandwidth based on changes to the offered rates of member queues. A minimum run interval is
enforced to allow a minimum amount of "batching" queue changes before reacting to the changed rates.
This minimum interval is beneficial since the periodic function of determining queue offered rates is per-
formed sequentially and the interval allows a number queues rates to be determined prior to determining the
distribution of bandwidth to the queues.
The default minimum scheduler run interval is 0.5 seconds. The sched-run-min-int command uses a percent
value to modify the default interval.
The no sched-run-min-int command is used to restore the default minimum scheduler run interval for all vir-
tual schedulers on the card.
Parameters
percent-of-default: — The percent-of-default parameter is required and is used to modify the default mini-
mum scheduler run interval for all virtual schedulers on the card. Defining 100.00 percent is equivalent to
removing the override (restoring the default) for the minimum scheduler run interval.
Values
Default
task-scheduling-int
Syntax task-scheduling-int percent-of-default
no task-scheduling-int
Context config>card>virt-sched-adj
Description
This command is used to override the system default time between scheduling the hierarchical virtual sched-
uling task. By default, the system "wakes" the virtual scheduler task every 50ms; this is equivalent to five
10ms timer ticks. The task-scheduling-int command uses a percent value parameter to modify the number of
timer ticks.
While the system accepts a wide range of percent values, the result is rounded to the nearest 10ms tick value.
The fastest wake interval is 10ms (1 timer tick).
The no scheduling-int command is used to restore the default task scheduling interval of the card's hierarchi-
cal virtual scheduler task.
