Service SAP QoS Policy Command Reference

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.
bytes — When byte is defined, the value given for size is interpreted as the queue’s MBS value
given in bytes.
kilobytes — When kilobytes is defined, the value is interpreted as the queue’s MBS value given
in kilobytes.
Values 0 – 16777216 or default
Default kilobyte
