Quality of Service Commands

Command Usage
• Use the
policy-map
command to specify a policy map and enter Policy Map
configuration mode. Then use the
class
command to enter Policy Map Class
configuration mode. And finally, use the
set
and
police
commands to specify
the match criteria, where the:
-
set
command classifies the service that an IP packet will receive.
-
police
command defines the maximum throughput, burst rate, and the
action that results from a policy violation.
•
You can configure up to 16 rules per Class Map. You can also include multiple
classes in a Policy Map
.
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.
set
This command services IP traffic by setting a CoS, DSCP, or IP Precedence value in
a matching packet (as specified by the
match
command on page 36-3). Use the
no
form to remove the traffic classification.
