What is Named and NumberACLs ?
Using numbered Access Control Lists (ACLs) is an effective method for determining the ACL type on smaller networks with more consistently defined traffic.
However, a number does not inform you of the function of the ACL. with Cisco IOS Release 11.2, this enables you to use a name to identify a Cisco ACL.
You assign a number based on which protocol you want filtered:
(1 to 99) and (1300 to 1999): Standard IP ACL
(100 to 199) and (2000 to 2699): Extended IP ACL
You assign a name by providing the name of the ACL:
Names can contain alphanumeric characters.
It is suggested that the name be written in CAPITAL LETTERS.
Names cannot contain spaces or punctuation and must begin with a letter.
You can add or delete entries within the ACL.
