Example
This example creates a policy called “rd_policy,” uses the
class
command to specify
the previously defined “rd_class,” uses the
set
command to classify the service that
incoming packets will receive, and then uses the
police
command to limit the
average bandwidth to 100,000 Kbps, the burst rate to 1522 bytes, and configure the
response to drop any violating packets.
Console(config)#policy-map rd_policy
Console(config-pmap)#class rd_class
Console(config-pmap-c)#set ip dscp 3
Console(config-pmap-c)#police 100000 1522 exceed-action drop
Console(config-pmap-c)#
police
This command defines an policer for classified traffic based on th e metered flow
rate. Use the no form to remove a policer.
Syntax
[no] police rate-kbps burst-byte [exceed-action {drop | set}]
• rate-kbps - Committed information rate in kil obi ts p er sec ond .
(Range: 1-100000 kbps or maximum port speed, whichever is lowe r)
• burst-byte - Committed burst size in bytes. (R ange: 64-52428 8 bytes)
• drop - Drop packet when specified rate or b urst are exc eeded.
• set - Set DSCP service to the specified value. (Range: 0-63 )
Default Setting
Drop out-of-profile packets.

Command Usage
• You can configure up to 64 p olicers (i.e ., mete rs or class maps) for e ach of the
following access list types: MAC ACL, IP ACL (including Standard ACL and
Extended ACL), IPv6 Standard ACL, and IPv6 Extended ACL. This limitation
applies to each switch chip (IC40240-10G: ports 1-26, IC40480-10G: ports 1-25,
ports 26-50).
• Policing is based on a token bucket, w here buck et depth (i.e ., the maxim um
burst before the bucket overflows) is by specified t he bu rst-byte field, and the
average rate tokens are removed fro m the b ucket is b y specifi ed by the
rate-bps option.
