Troubleshooting WCCP

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:

  1. Display WCCP stats
  2. Display WCCP config
  3. Display WCCP cache servers
  4. Display WCCP services
  5. Display WCCP assignment
  6. 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:

Sample output from the same command from an unsuccessful WCCP connection (because of a service group password mismatch):
