Troubleshooting WCCP
Two types of debug commands are available for debugging or troubleshooting a WCCP connection between a FortiGate unit operating as a WCCP router and its WCCP cache engines.
Real time debugging
The following commands can capture live WCCP messages:
diag debug en diag debug application wccpd <debug level>
Application debugging
The following commands display information about WCCP operations:
get test wccpd <integer> diag test application wccpd <integer> Where <integer> is a value between 1 and 6:
- Display WCCP stats
- Display WCCP config
- Display WCCP cache servers
- Display WCCP services
- Display WCCP assignment
- Display WCCP cache status
Enter the following command to view debugging output:
diag test application wccpd 3
Sample output from a successful WCCP connection:
service-0 in vdom-root: num=1, usable=1 cache server ID:
