llc2_config(1)

NAME

     llc2_config - configure LLC2 interface parameters

SYNOPSIS

     /usr/lib/llc2/llc2_config [-P | -U | -d  |  -q  |  -i ppa  |
     -r ppa]

DESCRIPTION

     The llc2_config utility is used to start/stop the LLC2  sub-
     system and to configure LLC2 interface parameters.

OPTIONS

     The following options are supported:

     -d    Turns on debug mode.  Extra debugging information will
           be printed out.

     -i ppa
           Initializes the corresponding interface using the file
           /etc/llc2/default/llc2.ppa.

     -P    Reads in  all  /etc/llc2/default/llc2.*  configuration
           files,  opens  those devices defined in the files, and
           sets up the streams needed for LLC2 to use those  dev-
           ices.  Before doing this, llc2_config -q will not show
           anything.

     -q    Queries the LLC2 subsystem. Information similar to the
           following  example  will  be  printed out for all PPAs
           (Physical Point of  Attachment)  available  under  the
           LLC2 module:

 PPA    State    ID      MACAddr         Type      MaxSDU    MinSDU    Mode
  0      up     0000   0800208a217e    ethernet     1500        0        3

             The fields displayed are described below:

           PPA   The relative logical position of the interface.

           State The state of the interface:

                  up   The interface is  initialized  and  opera-
                       tional.

                 down  The interface was "discovered" by the LLC2
                       driver, has passed its bootup diagnostics,
                       and is awaiting initialization.

                 bad   The interface is known to the LLC2 driver,
                       but  failed  one  or more of the integrity
                       checks performed at boot time. This  might
                       include  detecting  Interrupt  Request and
                       shared  memory   conflicts   or   failures
                       detected during the execution of the level
                       0 diagnostics.

           ID    The interface ID.

           MACAddr
                 The MAC address  currently  in  effect  for  the
                 interface.

           Type  The MAC type. Current types supported include:

                 csma/cd
                       10 Megabit Ethernet

                 ethernet
                       Ethernet type device

                 tkn-ring
                       4/16 Megabit Token Ring

                 fddi  100 Megabit Fiber Distributed Data  Inter-
                       face

           MaxSDU
                 The Maximum Service Data Unit  size  transmitted
                 on this interface.

           Mode  The Service Modes supported by  this  interface.
                 This field consists of the bitwise logical-ORing
                 of  the  supported  modes,   also   defined   in
                 /usr/include/sys/dlpi.h.

     -r ppa
           Uninitializes the corresponding  interface.  By  using
           this option, and then using the -i option, the parame-
           ters associated with an interface can be changed.

     -U    Destroys all streams used by the LLC2 subsystem.  This
           is  the  reverse of the -P option.  After this is exe-
           cuted, llc2_config -q will not show anything.
