Purpose: Layer 3—Finishes with the new form of the access group command, now able to refer to an IP access list name as well as an access list number.
Emphasize: Introduced with Cisco IOS Release 11.2, named access lists:
Intuitively identify IP access lists using alphanumeric identifiers.
Remove the limit on the number of access lists (previously 99 for IP standard and 100 for IP extended access lists).
Allow per-access-list-statement deletions (previously the entire numbered access list needed to be deleted as a single entity).
Require Cisco IOS Release 11.2 or later.
