The no form of this command returns the policy's min-thresh-separation value to the default value.
Default no min-thresh-separation
Parameters size [bytes | kilobytes] — The size parameter is required when executing the min-thresh-
[bytes | kilobytes] — The bytes keyword is optional and is mutually exclusive with the kilobytes

Syntax priority level
Context config>qos>policer-control-policy>root>priority-mbs-thresholds
Description The priority level command contains the mbs-contribution configuration command for a given strict
priority level. Eight levels are supported numbered 1 through 8 with 8 being the highest strict priority.
Each of the eight priority CLI nodes always exists and do not need to be created. While parameters
exist for each priority level, the parameters are only applied when the priority level within a parent
policer instance is currently supporting child policers.
Default None.
Quality of Service Guide
Note: A priority level's shared-portion of the parent policer's PIR bucket depth
is only necessary to provide some separation between a lower priority's discard-
all threshold and this priority's discard-unfair threshold. It is expected that the
burst tolerance for the unfair packets is relatively minimal since the child policers
feeding the parent policer priority level all have some amount of fair burst before
entering into an FIR exceed or unfair state. The fair burst amount for a priority
level is defined using the mbs-contribution command.
separation command. It is expressed as an integer and specifies the shared portion in bytes
or kilobytes that is selected by the trailing bytes or kilobytes keywords. If both bytes and
kilobytes are missing, kilobytes is the assumed value. Setting this value has no effect on
parent policer instances where the min-thresh-separation value has been overridden.
Values 0 to 4194304 or default (applies to the 7450 ESS)

The kilobytes keyword is optional and is mutually exclusive with the bytes keyword. When
specified, size is interpreted as specifying the size of min-thresh-separation in kilobytes.
