Creating QoS Policies
Use the Traffic > DiffServ (Configure Policy) page to create a policy map that can be
attached to multiple interfaces. A policy map is used to group one or more class
map statements (
page 220 ). A policy map can then be bound by a service policy to
one or more interfaces ( page 226 ).
Configuring QoS policies requires several steps. A class map must first be
configured which indicates how to match the inbound packets according to an
access list, a DSCP or IP Precedence value, a member of specific VLAN, or a CoS
value. A policy map must first be configured to indicate the boundary parameters
used for monitoring inbound traffic, and the action to take for conforming and
non-conforming traffic. A policy map may contain one or more classes based on
previously defined class maps.
In addition, the flow rate of inbound traffic can be monitored and the response to
conforming and non-conforming traffic set.
