To define a Class Map:
STEP 1 Click Quality of Service > QoS Advanced Mode > Class Mapping.
For each class map, the ACLs defined on it are displayed along with the relationship between
them. Up to three ACLs can be displayed along with their Match, which can be either And or
Or. This indicates the relationship between the ACLs. The Class Map is then the result of the
three ACLs combined with either And or Or.
STEP 2 Click Add.
A new class map is added by selecting one or two ACLs and giving the class map a name. If a
class map has two ACLs, you can specify that a frame must match both ACLs, or that it must
match either one or both of the ACLs selected.
STEP 3 Enter the parameters.
• Class Map Name—Enter the name of a new class map.
• Match ACL Type—The criteria that a packet must match in order to be considered to
belong to the flow defined in the class map. The options are:
- IP—A packet must match either of the IP based ACLs in the class map.
- MAC—A packet must match the MAC based ACL in the class map.
- IP and MAC—A packet must match the IP based ACL and the MAC based ACL in
the class map.
- IP or MAC—A packet must match either the IP based ACL or the MAC based ACL
in the class map.
• IP—Select the IPv4 based ACL or the IPv6 based ACL for the class map.
• MAC—Select the MAC based ACL for the class map.
• Preferred ACL—Select whether packets are first matched to an IP-based ACL or a
MAC-based ACL.
STEP 4 Click Apply. The Running Configuration file is updated.
Aggregate Policer
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.
