Access List Commands

Command	Description
`show access-lists`	Displays all access lists and their parameters configured on the router. This command doesn't show which interface the list is configured on.
`show access-list [list #]`	Shows only the parameters for the access list specified. This command does not show you the interface the list is configured on.
`show ip access-list`	Shows only the IP access lists configured on the router.
`show ipx access-list`	Shows only the IPX access lists configured on the router.
`show ip interface`	Shows which interfaces have IP access lists on them.
`show ipx interface`	Shows which interfaces have IPX access lists on them.
`show running-config`	Shows the access lists and which interfaces have access lists set.
`any`	Keyword used to represent all hosts or networks, replaces 0.0.0.0 255.255.255.255 in access list.
`host`	Keyword that specifies that an address should have a wildcard mask of 0.0.0.0 (i.e will match only 1 host)
`clear access-list counter [list#]`	Clears extended access lists counter of the number of matches per line of the access list.
`-1`	Applies to any IPX network or any protocol when used in extended IPX access lists.
`0`	Used for all sockets in extended IPX access lists.
`ip access-group`	Applies an IP access list to an interface.
`ipx access-group`	Applies an IPX access list to an interface.
`ipx input-sap-filter`	Applies an inbound IPX SAP filter to an interface.
`ipx output-sap-filter`	Applies an outbound IPX SAP filter to an interface.

Standard Access List Syntax

IP

   access-list 1-99 {permit|deny} address mask

Variable	Definition
`1-99`	Standard IP access lists are represented by a number ranging from 1-99 or text names with IOS 11.2 or greater.
`{permit\|deny}`	Used to specify the nature of the access list, either a permit or deny statement.
`address`	The IP address of the source.
`mask`	A wildcard mask, or inverse mask, applied to determine which bits of source address are significant.

IPX

   access-list 800-899 {deny|permit} source-network[.source-address[source-mask]]
                       destination-network[.destination-address[destination-mask]]

Variable	Definition
`800-899`	Standard IPX access lists are represented by a number ranging from 800-899.
`{deny\|permit}`	Used to specify the nature of the access list either a permit or deny statement.
`source-network[.source-address[source-mask]]`	The IPX address of the source network or node.
`destination-network[.destination-address[destination-mask]]`	The IPX address of the destination network or node.

Extended Access List Syntax

IP

 access-list 100-199 {permit|deny} {ip|tcp|udp|icmp} source source-mask [lt|gt|eq|neq]
 [source-port] destination dest-mask [lt|gt|eq|neq] [dest-port] [log]

Variable	Definition
`100-199`	Extended IP access lists are represented by a number ranging from 100-199 or text names with IOS 11.2 or greater.
`{permit\|deny}`	Used to specify the nature of the access list either a permit or deny statement.
`{ip\|tcp\|udp\|icmp}`	The IP protocol to be filtered can be IP (includes all protocols in the TCP/IP suite) TCP,UDP,ICMP,or others.
`source`	The IP address of the source
`source-mask`	A wildcard mask, or inverse mask, applied to determine which bits of source address are significant.
`[lt\|gt\|eq\|neq]`	Can contain lt (less than), gt (greater than), eq (equal to), or neq (not equal to). It is used if an extended list filters by a specific port number or range of ports.
`[source-port]`	If necessary, the source port number of the protocol to be filtered.
`destination`	The IP address of the destination
`dest-mask`	A wildcard mask, or inverse mask, applied to determine which bits of destination address are significant.
`[lt\|gt\|eq\|neq]`	Can contain lt (less than), gt (greater than), eq (equal to), or neq (not equal to). It is used if an extended list filters by a specific port number or range of ports.
`[dest-port]`	If necessary, the destination port number of the protocol to be filtered.
`[log]`	Turns on logging of access list activity.

IPX

 access-list 900-999 {deny|permit} protocol source-network.[source-address[source-mask]] socket
                     destination-network.[destination-address[dest-mask]] destination-socket

Variable	Definition
`900-999`	Extended IPX access lists are represented by a number ranging from 900-999.
`{deny\|permit}`	Used to specify the nature of the access list either a permit or deny statement.
`protocol`	IPX protocol, a -1 specifies all IPX protocols.
`source-network.[source-address[source-mask]]`	The IPX address of the source network or node.
`socket`	Source socket similar to the port value in IP access lists, points to a particular service, a 0 specifies all sockets.
`destination-network.[destination-address[dest-mask]]`	The IPX address of the destination network or node.
`socket`	Destination socket, similar to the port value in IP access lists, points to a particular service, a 0 specifies all sockets.
