16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series ip access-list ip access-list To create an IP access control list (ACL) to be used for matching packets to an ACL whose name or number you specify and to enter access-list configuration mode, use the ip access-list command in global configuration mode. To delete an existing IP ACL and return to global configuration mode, use the no form of this command. ip access-list {standard | extended} {name | access-list-number} no ip access-list {standard | extended} {name | access-list-number} Syntax Description name access-list-number Name of an ACL. Note The ACL name must begin with an alphabetic character to prevent ambiguity with numbered ACLs. A name also cannot contain a space or quotation mark. Number of an ACL. For standard IP ACLs, the range is from 1 to 99 and from 1300 to 1999. For extended IP ACLs, the range from 100 to 199 and from 2000 to 2699. Defaults No named or numbered IP ACLs are defined. Command Modes Global configuration Command History Release 12.1(6)EA2 12.2(15)ZJ Modification This command was introduced. This command was implemented on the following platforms: Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series routers. Usage Guidelines Use this command to specify the name or number of the IP ACL for which you want to create or modify ACL match criteria and to enter access-list configuration mode. In this mode, you must enter the permit and deny commands to configure the permit and deny access conditions for this list. The ip access-list command and its subcommands are used to define packet classification and marking as part of a globally-named service policy applied on a per-interface basis or as an IP access group applied on a per-interface basis. Specifying standard or extended with the ip access-list command determines the prompt you get when you enter access-list configuration mode. Note For more information about configuring IP ACLs, refer to the "Configuring IP Services" chapter in the Cisco IOS IP Configuration Guide, Release 12.2.
