Description
This command creates a classifier. A classifier defines a traffic flow. A
traffic flow consists of packets that share one or more characteristics. A
traffic flow can range from being very broad to being very specific. An
example of the former might be all IP traffic while an example of the
latter could be packets with specific source and destination MAC
addresses.
Classifiers are used with access control lists (ACL) and Quality of Service
policies. The classifiers define the traffic flow to be affected by the ACL or
QoS.
The ANY option of a parameter is used when you want to delete the
current setting of a parameter without setting a new value. This leaves
the parameter blank so that it applies to all packets.
Note
For definitions and restrictions on the classifier variables, refer to the
