NAME
     networkd -- network daemon.

SYNOPSIS
     networkd

DESCRIPTION
     networkd is a launch-on-demand daemon that performs opreations on behalf of code in libystem_network, a component of libSystem.

     networkd has no user-specifiable command-line argument, and users should not run networkd manually.

   LOGGING
     There are several methods with which to examine networkd's internal state for debugging and diagnostic purposes. The syslog(1) logging levels
     map as follows:

	   Error - Error messages
	   Warning - Non-fatal concerns
	   Notice - Internal state messages
	   Info - Informational messages

     By default, only log level Notice through Error is logged.

     Syslog may be used to modify the mask which logging levels are logged.  For example, to enable log levels Emergency - Debug :

	   % sudo syslog -c networkd -d

     The networkd settings file may also be used to change the log level.  This method will add some additional logging that may be missing using
     the syslog technique listed above. This method is also persistent across runs of networkd For example, to enable log levels Emergency (1)
     through Debug (7):

	   % sudo defaults write /Library/Preferences/com.apple.networkd networkd_log_level -int 7

     The networkd settings file may also be used to change the log level for code in libsystem_network. For example, to enable log levels Emer-
     gency (1) through Debug (7) for libsystem_network code:

	   % sudo defaults write /Library/Preferences/com.apple.networkd libnetcore_log_level -int 7

     A SIGINFO signal will dump a snapshot summary of the internal state to the system log at log level NOTICE :

	   % sudo killall -INFO networkd
