IP Access Lists
ACCESS LISTS Access lists allow Cisco routers to function as a packet filter and are supported for several protocols. The most common of these protocols are listed in the following table: Protocol Range IP standard 1 to 99 (and 1300 to 1999 in IOS 12.0 and higher) IP Extended 100-199 (and 2000 to 2699 in IOS 12.0 and higher) Ethernet type code 200-299 DecNet 300-399 XNS 400-499 Extended XNS 500-599 AppleTalk 600-699 Ethernet address 700-799 IPX Standard 800-899 IPX Extended 900-999 IPX SAP 1000-1099 Access lists are lists of rules that either permit or deny certain inbound or outbound traffic from and to particular hosts or networks. The access list and its rules are applied to one or more interfaces on the router.
