  0   Normal message level. Displays subsystem initialization messages,
      important	state changes, and significant error conditions. This is the
      default level for	the global_msg_level configuration attribute.

  1   Informational level. In addition to information displayed	at the previ-
      ous level, displays messages for normal virtual circuit (VC) release
      events, transient	errors,	and signaling and ILMI state changes.

  2   Verbose level. In	addition to information	displayed at the previous
      level, displays detailed information on connection failures, state
      changes, and unexpected events that is needed for	diagnosing ATM prob-
      lems.
