show ip wccp web-caches	Displays information about the router's known Cisco Cache Engines.

international

If you are Telneting to a Cisco IOS platform and you want to display 8-bit and multibyte international characters (for example, Japanese) and print the ESC character as a single character instead of as the caret and bracket symbols (^[), use the international line configuration command. Use the no form of this command to display characters in 7-bit format.

11.3	This command was introduced.

Usage Guidelines

If you are configuring a Cisco IOS platform using the Cisco Web browser interface, this feature is enabled automatically when you enable the Cisco Web browser using the ip http server command.

Examples

The following example enables a Cisco IOS platform to display 8-bit and multibyte characters and print the ESC character as a single character instead of as the caret and bracket symbols (^[) when you are Telneting to the platform:

international

Command	Description
terminal international	Prints the ESC character as a single character instead of as the caret and bracket symbols (^[) for a current Telnet session in instances when you are Telneting to a Cisco IOS platform and you want to display 8-bit and multibyte international characters (for example, Japanese).

ip wccp enable

To enable the router to support the Web Cache Control Protocol, use the ip wccp enable global configuration command. The no form of this command disables support for the Web Cache Control Protocol.

ip wccp enable

no ip wccp enable

Syntax Description

This command has no arguments or keywords.

Defaults

The Web Cache Control Protocol is disabled on the router.

Command Modes

Global configuration

Command History

Release	Modification
11.2 P, 11.1 CA	This command was introduced.

Usage Guidelines

This command and the ip web-cache redirect interface command are the only commands required to start redirecting requests to the Cisco Cache Engine using the Web Cache Control Protocol. To see if the Web Cache Control Protocol is enabled on the router, use the show ip wccp command.

When this command is enabled but the ip web-cache redirect command is disabled, the router is aware of caches but does not use them.

Use the ip wccp redirect-list command to limit the redirection of packets to those matching an access list.

Examples

The following example configures a router to support the Web Cache Control Protocol and redirects web-related packets from Ethernet interface 0 to the Cisco Cache Engine:

Router# configure terminal

Router(config)# ip wccp enable

Router(config)# interface Ethernet 0

Router(config-if)# ip web-cache redirect

Router(config-if)# end

Router#

%SYS-5-CONFIG_I: Configured from console by console.

Related Commands

Command	Description
ip wccp redirect-list	Specifies which packets are redirected to a Cisco Cache Engine.
ip web-cache redirect	Instructs an interface to check for appropriate outgoing packets and redirect them to a Cisco Cache Engine.
show ip wccp	Displays global statistics related to the Web Cache Control Protocol.
show ip wccp web-caches	Displays information about the router's known Cisco Cache Engines.

ip wccp redirect-list

To specify which packets are redirected to a Cisco Cache Engine, use the ip wccp redirect-list global configuration command. The no form of this command enables redirection of all packets.

ip wccp redirect-list {number | name}

Syntax Description

number	Standard or extended IP access list number from 1 to 199.
name	Standard or extended IP access list name. This argument is only available in Release 11.2 P.

Defaults

All HTTP packets are redirected to the Cisco Cache Engine.

Command Modes

Global configuration

Command History

Release	Modification
11.2 P, 11.1 CA	This command was introduced.

Usage Guidelines

Use this command to specify which packets should be redirected to the Cisco Cache Engine. When WCCP is enabled but this command is not configured, all web-related packets are redirected to the Cisco Cache Engine. When you enter this command, only packets that match the access list are redirected.

Some Web sites use the source IP address of packets for authentication. The Cisco Cache Engine uses its own IP address when sending requests to Web sites. Thus, the requests from the Cisco Cache Engine may not be authenticated. Use this command to bypass the Cisco Cache Engine in these cases.

Use the ip wccp enable and ip web-cache redirect commands to configure WCCP.

Examples

The following example configures a router to redirect web-related packets without a destination of 192.168.196.51 to the Cisco Cache Engine:

Router# configure terminal

Router(config)# access-list 100 deny ip any host 192.168.196.51

Router(config)# access-list 100 permit ip any any

Router(config)# ip wccp enable

Router(config)# ip wccp redirect-list 100

Router(config)# interface Ethernet 0

Router(config-if)# ip web-cache redirect

Router(config-if)# end

Router#

%SYS-5-CONFIG_I: Configured from console by console.

show ip wccp	Displays global statistics related to the Web Cache Control Protocol.

ip web-cache redirect

To instruct an interface to check for appropriate outgoing packets and redirect them to a Cisco Cache Engine, use the ip web-cache redirect interface configuration command. The no form of this command disables the redirection of messages to the Cisco Cache Engine.

ip web-cache redirect

Syntax Description

type	(Optional) Interface type.
number	(Optional) Interface number.

Command Modes

EXEC

Command History

Release	Modification
10.0	This command was introduced.

Usage Guidelines

The Cisco IOS software automatically enters a directly connected route in the routing table if the interface is usable. A usable interface is one through which the software can send and receive packets. If the software determines that an interface is not usable, it removes the directly connected routing entry from the routing table. Removing the entry allows the software to use dynamic routing protocols to determine backup routes to the network (if any).

If the interface can provide two-way communication, the line protocol is marked "up." If the interface hardware is usable, the interface is marked "up."

If you specify an optional interface type, you will see only information on that specific interface.

If you specify no optional arguments, you will see information on all the interfaces.

When an asynchronous interface is encapsulated with PPP or SLIP, IP fast switching is enabled. A show ip interface command on an asynchronous interface encapsulated with PPP or SLIP displays a message indicating that IP fast switching is enabled.

Examples

The following is sample output from the show ip interface command:

Router# show ip interface

Ethernet0 is up, line protocol is up

  Internet address is 192.195.78.24, subnet mask is 255.255.255.240
