Quality of Service
3-157
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 3-154.
• 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 3-153). 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 (ES4524D:
ports 1-26, ES4548D: ports 1-25, ports 26-50). Also, note that the maximum
number of classes that can be applied to a policy map is 16.
Policing is based on a token bucket, where bucket depth (i.e., 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.
• After using the policy map to define packet classification, service tagging, and
bandwidth policing, it must be assigned to a specific interface by a service policy
to take effect.
