default, discards ingress packets that match the defined traffic flow of
the classifier. Permit accepts the packets. The default is Deny.

Use this field to enter a description for the ACL. A description can be
up to 15 alphanumeric characters, including spaces. Entering a
description is optional.

An ACL that is not assigned to any port is considered inactive.
