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), IPv6 Standard ACL, and IPv6 Extended ACL. This limitation
applies to each switch chip (ES3528M-SFP: ports 1-28).
• 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.
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.
service-policy
This command applies a policy map defined by the policy-map command to the
ingress queue of a particular interface. Use the no form to remove the policy map
from this interface.

the service-policy command to bind the policy map to the required interface.
