Syntax high-prio-only percent

Context config>qos>network-queue>queue
Description The high-prio-only command allows the reservation of queue buffers for use exclusively by
in-profile packets as a default condition for access buffer queues for this network queue
policy. For network queues, in-profile packets are high priority, and out-of-profile packets are
low priority.
Modifying the current MBS for the queue through the mbs command will cause the default
high-prio-only function to be recalculated and applied to the queue.
The no form of this command restores the default value.
Default Table 40 lists the high-prio-only forwarding class defaults.
Parameters percent — the amount of queue buffer space reserved for in-profile packets, expressed
as a decimal percentage
Values 0 to 100 | default
Note: When a low-priority RED/WRED slope is enabled on a queue, the high-prio-only
setting is not used. When that slope is disabled, then the high-prio-setting is used.
