QoS Policers

You can measure the rate of traffic that matches a pre-defined set of rules, and to enforce limits, such as limiting the rate of file-transfer traffic that is allowed on a port.

This can be done by using the ACLs in the class map(s) to match the desired traffic, and by using a policer to apply the QoS on the matching traffic.

NOTE     QoS policers are not supported when the switch is in Layer 3 mode.

A policer is configured with a QoS specification. There are two kinds of policers:

Each policer is defined with its own QoS specification with a combination of the following parameters:

Assigning a policer to a class map is done when a class map is added to a policy. If the policer is an aggregate policer, you must create it using the Aggregate Policer page.
