The acl Statement

Syntax

acl name {
  address_match_list
};

Definition and Usage

The acl statement creates a named address match list. It gets its name from a primary use of address match lists: Access Control Lists (ACLs).

Note that an address match list's name must be defined with acl before it can be used elsewhere; no forward references are allowed.

The following ACLs are built-in:

Any	Allows all hosts.
None	Denies all hosts.
Localhost	Allows the IP addresses of all interfaces on the system.
Localnets	Allows any host on a network for which the system has an interface.
