Information About Extended ACLs
ACLs are used to control network access or to specify traffic for many features to act upon. An extended
ACL is made up of one or more access control entries (ACEs). Each ACE specifies a source and
destination for matching traffic. You can identify parameters within the
access-list
command, or you can
create objects or object groups for use in the ACL.

Access Control Entry Order
An ACL is made up of one or more ACEs. Each ACE that you enter for a given ACL name is appended
to the end of the ACL.
The order of ACEs is important. When the security appliance decides whether to forward or drop a
packet, the security appliance tests the packet against each ACE in the order in which the entries are
listed. After a match is found, no more ACEs are checked. For example, if you create an ACE at the
beginning of an ACL that explicitly permits all traffic, no further statements are ever checked.
You can disable an ACE by making it inactive.
