police cir percent
Examples
This example shows how to configure traffic policing by using a CIR and a PIR based on a percentage
of bandwidth. In this example, a CIR of 20 percent and a PIR of 40 percent are specified. The optional
bc
and
be
values (300 ms and 400 ms, respectively) are specified.

This example shows how to create two hierarchical policies, one called
child_policy
and one called
parent_policy
. In the
child_policy
policy-map, the
police cir percent
command is configured in the class
called
normal_type
. In this class, the percentage specified by the
police cir percent
command is 30
percent. The command uses 512 kbps, the peak rate (specified in the
parent_policy
through the
shape
average 512000
command), as the bandwidth reference point for the
class parent
in the
parent_policy
.
The
police cir percent
command uses 512 kbps as the basis for calculating the CIR rate (512 kbps * 30
percent).

This example shows how to create two hierarchical policies, one called
child_policy
and one called
parent_policy
. In the
child_policy
policy map, the
police cir percent
command is configured in the class
called
normal_type
. In this class, the percentage specified by the
police cir percent
command is 30
percent. In the
parent_policy
, a peak rate is not specified. The
bandwidth
policy-map class
configuration command is used, but this command does not represent the maximum rate of bandwidth
available. Therefore, the
police cir percent
command uses the next higher level (Gigabit Ethernet port)
as the bandwidth reference point. Assuming the bandwidth of the port is 1 Mbps, the
police cir percent
command uses 1 Mbps as the basis for calculating the CIR rate (1000000 * 30 percent).
