Troubleshooting WCCP and related data collection COMMANDS

On Router:


1. show version
2. show ip wccp
3. show ip wccp interface detail
4. show ip wccp <service> service
5. show ip wccp <service> detail
6. show ip wccp <service> internal
7. show ip wccp <61 / 62> hash



Repeat commands 4, 5 and 6 for each active service (as indicated by “show ip wccp”).

1. show process cpu history

2. show process cpu | exclude 0.00



Repeat this command 6-8 times in order to try and identify a particular process that is eating up the CPU.

1. debug ip wccp events

2. debug ip wccp packets




The debugging output can be fairly verbose, so it is probably best to turn off console logging and log the debugs to a buffer. When done capture the results via “show log” – make sure you capture everything, some terminal emulators can “chop off” text beyond 80 characters.
