Configuring a Classifier
This procedure explains how to create an ACL. It is a good idea before
performing this procedure to jot down on paper the ID number(s) of the
classifier(s) you want to assign to the ACL and the action of the ACL,
which is either Permit or Deny. An action of Permit instructs the port to
accept packets from the defined traffic flow of the classifier, while an
action of Deny discards the packets. Having this information handy will
make it easier for you to perform the procedure. To view the classifier ID
numbers and specifications, refer to “Displaying the Access Control Lists”
on page 178.
To configure a classifier, perform the following procedure:
1. From the home page, select Configuration.
The System page is displayed with the General tab selected by
default, as shown in Figure 5 on page 38.
Note
You can access the Classifiers tab either through the Network
Security menu option or through the Services menu option. This
procedure uses the path through the Network Security menu option.
2. From the Configuration menu, select the Network Security option.
The Network Security page is displayed with the Port Security tab
selected by default, as shown in Figure 158 on page 392.
3. Select the Classifier tab.
