show ip wccp

show ip wccp

To display the IPv4 Web Cache Communication Protocol (WCCP) global configuration and statistics, use the show ip wccp command in user EXEC or privileged EXEC mode.

show ip wccp [ all ] [capabilities] [summary] [ interfaces [ cef | counts | detail ] ] [ vrf vrf-name ] [ { web-cache | service-number } [assignment] [clients] [counters] [detail] [service] [view] ]

Syntax Description

all	(Optional) Displays statistics for all known services.

12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.4(11)T	This command was enhanced to display information about the WCCP service mode.
12.2(33)SXH	This command was integrated into Cisco IOS Release 12.2(33)SXH.
Cisco IOS XE Release 2.2	This command was integrated into Cisco IOS XE Release 2.2.
15.0(1)M	This command was modified. The summary keyword and the vrf vrf-name keyword and argument pair were added.

12.2(50)SY	This command was modified. The summary keyword and the vrf vrf-name keyword and argument pair were added.
15.2(3)T	This command was integrated into Cisco IOS Release 15.2(3)T.
15.1(1)SG	This command was integrated into Cisco IOS Release 15.1(1)SG.
Cisco IOS XE Release 3.3SG	This command was integrated into Cisco IOS XE Release 3.3SG.
Cisco IOS XE 3.3SE	This command was implemented in Cisco IOS XE Release 3.3SE.

Usage Guidelines

Use the clear ip wccp command to reset all WCCP counters.

Use the show ip wccp service-number detail command to display information about the WCCP client timeout interval and the redirect assignment timeout interval if those intervals are not set to their default value of 10 seconds.

Use the show ip wccp summary command to display the configured WCCP services and a summary of their current state.

On Cisco ASR 1000 Series Aggregation Services Routers, nonzero values can only be seen for platform-specific counters because Cisco ASR 1000 Series Routers implement all redirection in hardware. Configuring the counters keyword also displays counters received in hardware.

Table 3 show ip wccp service-number detail Field Descriptions
Field	Description
Protocol Version	Indicates whether WCCPv1 or WCCPv2 is enabled.
State	Indicates whether the WCCP client is operating properly and can be contacted by a router and other clients in the service group. When a WCCP client has an incompatible message interval setting, the state of the client is shown as "NOT Usable," followed by a status message describing the reason why the client is not usable.
Redirection	Indicates the redirection method used. WCCP uses GRE or L2 to redirect IP traffic.
Assignment	Indicates the load-balancing method used. WCCP uses HASH or MASK assignment.
Connect Time	The amount of time the client has been connected to the router.
Redirected Packets	The number of packets that have been redirected to the content engine.

Examples

The following example displays WCCP client information and WCCP router statistics that include the type of services:

Router# show ip wccp 91 clients

The table below describes the significant fields shown in the display.

Table 4 show ip wccp service-number clients Field Descriptions
Field	Description
Protocol Version	Indicates whether WCCPv1 or WCCPv2 is enabled.
State	Indicates whether the WCCP client is operating properly and can be contacted by a router and other clients in the service group. When a WCCP client has an incompatible message interval setting, the state of the client is shown as "NOT Usable," followed by a status message describing the reason why the client is not usable.
Redirection	Indicates the redirection method used. WCCP uses GRE or L2 to redirect IP traffic.
Assignment	Indicates the load-balancing method used. WCCP uses HASH or MASK assignment.
Connect Time	The amount of time (in seconds) the client has been connected to the router.
Redirected Packets	The number of packets that have been redirected to the content engine.
