WCCP Testing and Troubleshooting
When working with WCCP, the appliance provides different ways of monitoring the status of the WCCP interface, and your router should also provide information.
Monitoring: Appliance Performance: WCCP Page—The WCCP page reports the current state of the WCCP link, and reports most problems.
Log Entries—The Monitoring: Appliance Performance: Logging page shows a new entry each time WCCP mode is established or lost.

Router Status—On the router, the “show ip wccp” command shows the status of the WCCP link:
