no police cir percent percent [bc conform-burst-in-msec] [pir percent percentage] [be
peak-burst-inmsec]
Syntax Description
Command Default This command is disabled by default.
cir Committed information rate. Indicates that the CIR will be used for policing
traffic.
percent Specifies that a percentage of bandwidth will be used for calculating the
CIR.
percent Specifies the bandwidth percentage. Valid range is a number from 1 to 100.
bc (Optional) Conform burst (bc) size used by the first token bucket for policing
traffic.
conform-burst-in-msec (Optional) Specifies the bc value in milliseconds. Valid range is a number
from 1 to 2000.
pir (Optional) Peak information rate (PIR). Indicates that the PIR will be used
for policing traffic.
