Description
The cbs command is used to define the default committed buffer size for the template queue or the
CBS for the template policer. Overall, the cbs command follows the same behavior and provisioning
characteristics as the cbs command in the SAP ingress and egress QoS policy.
The no form of this command restores the default CBS size to the template policer.

limit size. The value is expressed as an integer and by default is interpreted as the burst limit
in Kilobytes. If the value is intended to be interpreted in bytes, the byte qualifier must be
added following size.
Values 1 to 14,000 (14,000 or 14,000,000 depending on bytes or
kilobytes)

exclusive with the bytes qualifier. If neither bytes nor kilobytes is specified, the default

kilobytes reserved for 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). For policers, the size parameter is an integer
expression of the number of kilobytes for the policer CBS.
