Guidelines

Follow these guidelines when creating a classifier:

 Each classifier represents a separate traffic flow.

 The variables within a classifier are linked by AND. The more variables

defined within a classifier, the more specific it becomes in terms of the

flow it defines. For instance, specifying both a source IP address and a

TCP destination port within the same classifier defines a traffic flow

that relates to IP packets containing both the designated source IP

address and TCP destination port. However, there are some

restrictions on combining variables in the same classifier. See

“Classifier Criteria” on page 187.

 You can apply the same classifier to more than one access control

policy.

 A classifier without any defined variables applies to all packets.

 You cannot create two classifiers that have the same settings. There

can be only one classifier for any given type of traffic flow.

 The switch can store up to 256 classifiers. However, the maximum

number of classifiers that you can assign to active access control

policies at any one time is 64.
