CLI - This example creates a class map call “rd-class,” and sets it to match
packets marked for DSCP service value 3.
6.15.1.2 Creating QoS Policies
This function creates a policy map that can be attached to multiple interfaces.
Command Usage
• To configure a Policy Map, follow these steps:
• Create a Class Map as described on page 343.
• Open the Policy Map page, and click Add Policy.
• When the Policy Configuration page opens, fill in the “Policy Name”
field, and click Add.
• When the Policy Rule Settings page opens, select a class name
from the scroll-down list (Class Name field). Configure a policy for
traffic that matches criteria defined in this class by setting the quality
of service that an IP packet will receive (in the Action field), defining
the maximum throughput and burst rate (in the Meter field), and the
action that results from a policy violation (in the Exceed field). Then
finally click Add to register the new policy.
• A policy map can contain multiple class statements that can be applied
to the same interface with the Service Policy Settings (page 350). Up to
63 policers (that is, class maps) can be configured for Fast Ethernet and
Gigabit Ethernet ingress ports.
Policing is based on a token bucket, where bucket depth (that is, the
maximum burst before the bucket overflows) is by specified the “Burst”
field, and the average rate tokens are removed from the bucket is by
specified by the “Rate” option.
