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.
police
This command defines an policer for classified traffic. Use the no form to remove a
policer.
Syntax
[no] police rate-kbps burst-byte [exceed-action {drop | set}]
• rate-kbps - Rate in kilobits per second. (Range: 1-100000 kbps or maximum
port speed, whichever is lower)
• burst-byte - Burst in bytes. (Range: 64-1522 bytes)
• drop - Drop packet when specified rate or burst are exceeded.
• set - Set DSCP service to the specified value. (Range: 0-63)
Default Setting
Drop out-of-profile packets.
Command Mode
Policy Map Class Configuration
Command Usage
• You can configure up to 64 policers (i.e., meters or class maps) for each of the
following access list types: MAC ACL, IP ACL (including Standard ACL and
Extended ACL).
• Policing is based on a token bucket, where bucket depth (i.e., the maximum
burst before the bucket overflows) is specified by the burst-byte field, and the
average rate at which tokens are removed from the bucket is specified by the
rate-bps option.
