492 Quality of Service
The following is an example of the CLI commands:
Aggregate Policer
The rate of traffic that matches a pre-defined set of rules can be measured,
and limits, such as limiting the rate of file-transfer traffic that is allowed on a
port, can be enforced.
This is done by using the ACLs in the class map(s) to match the desired
pattern of traffic, and by using a policer to apply QoS on the matching traffic.
A policer is configured with a QoS specification. There are two kinds of
policers:
• Single Policer — A single policer applies the QoS to a single class map,
and to a single flow, based on the policer's QoS specification. When a class
map, using a single policer, is bound to multiple ports, each port has its
own instance of the single policer; each applying the QoS on the class map
(flow) at ports that are otherwise independent of each other. A single
policer is created in the
Policy Table and Policy Class Maps pages.
match access-group acl-name
no match access-group acl-name
Defines the match criteria for
classifying traffic.
Use the no form of this command to
delete the match criteria.
show class-map [class-map-name] Displays information about the class
map.
console(config)# qos advanced
console(config)# class-map class1 match-all
console(config-cmap)# match access-group enterprise
console(config-cmap)# do show class-map class1
Class Map matchAll class1
Match access-group enterprise
