The WSS is unusable.

Action must be taken immediately.

You must resolve the critical conditions. If the conditions are not 
resolved, the WSS can reboot or shut down.

The WSS is missing data or is unable to form a connection.

A possible problem exists.

Events that potentially can cause system problems have occurred. These 
are logged for diagnostic purposes. No action is required.

Informational messages only. No problem exists.

Output from debugging.

Note: The debug level produces a lot of messages, many of which can 
appear to be somewhat cryptic. Debug messages are used primarily by 
Nortel for troubleshooting and are not intended for administrator use.
