hi-low-prio-only
Syntax hi-low-prio-only percent
no hi-low-prio-only
Context config>qos>sap-egress>queue
config>qos>qgrps>egr>qgrp>queue
Description The hi-low-prio-only command configures the percentage of buffer space for the queue, used
exclusively by higher priority (in-profile and out-of-profile) packets. The specified value overrides the
default value for the context. It is applicable to SAP egress QoS policy queues and egress queue group
template queues.
The priority of a packet can only be set in the SAP ingress QoS policy and is only applicable on the
ingress queues for a SAP. At SAP egress, the priority of a packet is based on its profile state. The no
form of this command restores the default higher priority reserved size.
The hi-low-prio-only drop tail exists also for egress network queues in a network queue policy,
however, in these policies it is not configurable and has a default of an additional 10% of the MBS
value on top of the high priority only.
Default 20%
Parameters percent — The percentage reserved for higher priority (in-profile and out-of-profile) traffic on the
queue.
