Types of Access Lists

Basically there are two major types of access lists.

Standard Access list

It provides basic filtering options to the route. To explain, an example is here, a standard IP access list will only allow the source address of a data packet to be used in filtering the decisions. If you just want to stop some selected host to join in the network and there are no serious complexities in it then you can use standard access list.

Extended Access list

It allows filtering to be done in many different ways using different parameters. As an example, an extended IP access list allows data packets to be managed according to source address, destination address, protocol type, port numbers or any other parameter if there are complexities in your network and you want to block some activities of some specific hosts then you can use the extended access list.
Following are some access lists identified numerically to help you. The numerical value not only identifies the list uniquely that it is extended or standard. The lists below define the outlines foe different access lists.

1-99 IP standard access list
100-199 IP extended access list
200-299 Protocol type-code access list
300-399 DECnet access list
400-499 XNS standard access list
500-599 XNS extended access list
600-699 AppleTalk standard access list
700-799 AppleTalk extended access list
800-899 IPX standard access list
900-999 IPX extended access list
1000-1099 IPX SAP access list
1100-1199 Extended 48-bit MAC address access list
1200-1299 IPX summary address access list

The numerical value “87” is assigned to the standard access list. That is only for standard list. The number “907” defines the value foe extended list. It is upon you that what number you give to your access list. You are free to give ant number. Just take care of the thing,that remember what value you have given to it.
