closest — The closest keyword is used to inform the system that the metering rate defined for the policer is
the target rate. The system will choose a hardware supported rate that is closest to the specified rate.
Default
cir {max | min | closest} — When the optional cir parameter is specified, the max, min or closest keyword
qualifier must follow.
max — The max keyword is used to inform the system that the profiling rate defined for the policer is the
maximum allowed rate. The system will choose a hardware supported rate that is closest but not
exceeding the specified rate.
min — The min keyword is used to inform the system that the profiling rate defined for the policer is the
minimum allowed rate. The system will choose a hardware supported rate that is closest but not lower
than the specified rate.
closest — The closest keyword is used to inform the system that the profiling rate defined for the policer is
the target rate. The system will choose a hardware supported rate that is closest to the specified rate.

Description
This command is used to configure the policer's CIR leaky bucket's exceed threshold. The CIR bucket's
exceed threshold represents the committed burst tolerance allowed by the policer. If the policer's forwarding
rate is equal to or less than the policer's defined CIR, the CIR bucket depth hovers around the 0 depth with
spikes up to the maximum packet size in the offered load. If the forwarding rate increases beyond the
profiling rate, the amount of data allowed to be in-profile above the rate is capped by the threshold.
The policer's cbs size defined in the QoS policy may be overridden on an sla-profile or SAP where the
policy is applied.
The no form of this command returns the policer to its default CBS size.
Default 64 kilobytes when CIR = max, otherwise, 10ms volume of traffic for a configured non zero/non max CIR.
Parameters size [bytes | kilobytes] — The size parameter is required when specifying cbs and is expressed as an integer
representing the required size in either bytes or kilobytes. The default is kilobytes. The optional byte
and kilobyte keywords are mutually exclusive and are used to explicitly define whether size represents
bytes or kilobytes.
byte — When byte is defined, the value given for size is interpreted as the queue's MBS value given in
bytes.
kilobyte — When kilobytes is defined, the value is interpreted as the queue's MBS value given in kilobytes.
