acl acl-name {
address_match_list
};
6.2.2. acl Statement Definition and Usage
The acl statement assigns a symbolic name to an 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 Matches all hosts.
none Matches no hosts.
localhost Matches the IPv4 addresses of all network interfaces on the system.
