The no form of this command restores the default CBS size to the template queue.
Default default
Parameters size-in-kbytes — The size parameter is an integer expression of the number of kilobytes reserved for the
queue. If a value of 10KBytes is desired, enter the value 10. A value of 0 specifies that no reserved buf-
fers are required by the queue (a minimal reserved size can still be applied for scheduling purposes).

Description The high-prio-only command specifies the percentage of buffer space for the queue, used exclusively by
high priority packets. The specified value overrides the default value for the context.
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. The high-prio-only parameter is used to override the default value derived from the net-
work-queue command.
The no form of this command restores the default high priority reserved size.
Parameters percent — The percentage reserved for high priority traffic on the queue. If a value of 10KBytes is desired,
enter the value 10.
Values
mbs
Syntax mbs size-in-kbytes
no mbs

Description The Maximum Burst Size (MBS) command specifies the default maximum buffer size for the template
queue. The value is given in kilobytes.
The MBS value is used by a queue to determine whether it has exhausted all of its buffers while enqueuing
packets. Once the queue has exceeded the amount of buffers allowed by MBS, all packets are discarded until
packets have been drained from the queue.
The queue-group or network egress QoS context for mbs provides a mechanism for overriding the default
maximum size for the queue.
