Action
Use this menu to specify the action of the ACL. An action of Permit
means the port accepts the packets that meet the criteria of the
classifiers assigned to the ACL. An action of Deny means the port
discards the packets, unless the packets also match the criteria of a
Permit ACL, in which case the packets are accepted by the port,
because a Permit ACL overrides a Deny ACL.
Description
Use this field to enter a description for the ACL. A description can be
up to 15 alphanumeric characters, including spaces. A description is
optional.
Port List
Use this list to specify the port where the ACL is to be assigned. You
can assign an ACL to more than one port. To select multiple ports,
hold down the Ctrl key while making your selections. You do not have
to assign an ACL to a port when you initially create it. However, an
ACL remains inactive until it is assigned to a port.
6. Click Apply.
The new ACL is immediately activated on the specified ports. If you did
not specify any ports for the ACL, the ACL is created but remains
inactive until you assign it to a port.
7. To permanently save your changes, select the Save Config option in
the Configuration menu.
