4. Type 1 to select ACL ID and, when prompted, enter an ID number for

the ACL. Every ACL on the switch must have a unique ID number. The
range is 0 to 255. The default is the lowest unused number. This
parameter is required.

5. Type 2 to select Description and enter a description for the ACL. A

description can be up to 31 alphanumeric characters. Spaces are
allowed. This parameter is optional, though recommended. Assigning
the ACLs different names will make it easier for you to identify them.

6. Type 3 to select Action.

The following prompt is displayed:

Enter Value [0 - Deny, 1 - Permit] : [0 to 1] -> 0

7. Type 0 if you want the ACL to discard ingress packets that meet the

criteria in the classifiers to be assigned to the ACL or 1 if the packets
are to be accepted. The default setting is Deny.

8. Type 4 to select Classifier List from the Create ACL menu and, when

prompted, enter the classifiers to be assigned to the ACL. The prompt
includes the ID numbers of the classifiers on the switch. You can
assign more than one classifier to an ACL. Multiple classifiers are
separated by a comma (for example, 4,7,2). The order in which you
specify the classifiers is not important.

When entering classifiers, keep in mind the action that you specified
for this ACL in step 7. The action and the traffic flows defined by the
classifiers should correspond. For instance, an ACL with an action of
permit should be assigned those classifiers that define the traffic flow
you want the ports to accept.

9. Type 5 to select Port List and, when prompted, enter the ports where

you want to assign the ACL. You can assign an ACL to just one port or
to more than one port. When entering multiple ports, the ports can be
listed individually (e.g., 2,5,7), as a range (e.g., 8-12) or both (e.g., 1-
4,6,8).

10. Type C to select Create ACL.

The ACL is created on the switch and immediately activated on the
specified ports.

11. To create additional ACLs, repeat this procedure starting with step 3.

12. After making changes, type R until you return to the Main Menu. Then

type S to select Save Configuration Changes.
