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.*  configura-
               tion  files,  opens  those  devices defined in the
               files, and sets up the streams needed for LLC2  to
               use those devices.  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 operational.

     -r ppa    Uninitializes  the  corresponding  interface.   By
               using  this  option, and then using the -i option,
               the parameters 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 executed, llc2_config -q  will  not  show  any-
               thing.
