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.

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.
