Troubleshooting RADIUS

Command	Purpose

Router# clear ssg service service-name	Removes the specified service.

Router# debug ssg ctrl-errors	Displays all error messages for control modules.

Router# debug ssg ctrl-events	Displays all event messages for control modules.

Router# debug ssg ctrl-packets	Displays packet contents handled by control modules.

Router# debug ssg data	Displays all data-path packets.

Router# debug ssg data access-list number	Displays all data-path packets for the specified access list.

Router# debug ssg errors	Displays all error messages for system modules.

Router# debug ssg events	Displays event messages for system modules.

Router# debug ssg packets	Displays packet contents handled by system modules.

Troubleshooting RADIUS

To troubleshoot communication between the RADIUS server and SSG, enter the debug radius command in privileged EXEC mode.

Per-Service Statistics

The Cisco 10000 series router collects statistics about router interfaces and the connections to them in both the input and output directions. Cisco CLI commands, such as show interface, are used to display information about the interfaces. SSG commands, such as show ssg connection, are used to display information about the connection to the router.

Restrictions for Per-Service Statistics

The Per-Service Statistics feature has the following restrictions:

•The Cisco 10000 series router does not collect connection level statistics for the default or Open Garden network.

•You cannot display the aggregate statistics for a user.

•For PPP-based users, any link level control traffic, such as keepalives, are counted separately from the data traffic to support idle timeouts.
