  15.      _t_g_c_m_d is the diagnostic utility for the Tigon3 gigabit Ethernet driver
  16.      _t_g(7M).  It supports a number of subcommands to interrogate and control
  17.      both the driver itself and the Tigon3 interfaces ('tgN') under its
  18.      control.  Typing _t_g_c_m_d with no arguments outputs a usage message which
  19.      lists all of the available subcommands.
  20.  
  21. WWWWAAAARRRRNNNNIIIINNNNGGGG
  22.      Only some of the _t_g_c_m_d subcommands are documented here.  The remaining
  23.      (undocumented) subcommands should be executed only under the direction of
  24.      Silicon Graphics service personnel - they could adversely affect system
  25.      performance or functionality.

  49.           Displays the configuration parameters currently in effect for the
  50.           specified interface.  The parameter values that are displayed with
  51.           this command differ from the "saved configuration" displayed by
  52.           _t_g_c_o_n_f_i_g(1M), in that they have been decoded from their original
  53.           string values, and the defaults have been resolved.
  54.  
  55.           This decoding and resolution step occurs when the interface is
  56.           brought up, so if '_t_g_c_o_n_f_i_g -s' is used to change the configuration
  57.           of an interface that is already up, '_t_g_c_o_n_f_i_g -g' will display the
  58.           new configuration and '_t_g_c_m_d configs _t_g_N' will display the old
  59.           configuration that is still in effect.

  164.      at least one Tigon3 card in the system.  This error message most likely
  165.      indicates that no Tigon3 cards were recognized by the driver. Use the
  166.      _h_i_n_v(1M) command to verify the presence of Tigon3 cards.
