Description
The cbs command is used to define the default committed buffer size for the template queue. Overall,
the cbs command follows the same behavior and provisioning characteristics as the cbs command in
the SAP ingress QoS policy. The exception is the addition of the cbs-value qualifier keywords bytes
or kilobytes.
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

id rate command. The cir parameter requires a qualifier that defines the constraint used when
deriving the operational CIR for the queue. When the cir parameter is not specified, the default
constraint applies.
PIR value.
Values max — The max (maximum) option is mutually exclusive with the min and closest
options. When max is defined, the operational PIR for the queue will be equal to or
less than the administrative rate specified using the rate command.
min — The min (minimum) option is mutually exclusive with the max and closest
options. When min is defined, the operational PIR for the queue will be equal to or
greater than the administrative rate specified using the rate command.
closest — The closest parameter is mutually exclusive with the min and max
parameter. When closest is defined, the operational PIR for the queue will be the
rate closest to the rate specified using the rate command.
the queue. If a value of 10KBytes is desired, enter the value 10. A value of 0 specifies that no
reserved buffers are required by the queue (a minimal reserved size can still be applied for
scheduling purposes).
Values
0 — 131072 or default
