llc2_config(1) User Commands llc2_config(1)NAMEllc2_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 subsystem 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 devices. Before doing
this, llc2_config-q will not show anything.
-q Queries the LLC2 subsystem. Information similar to the follow‐
ing 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 inter‐
face.
State The state of the interface:
up The interface is initialized and
operational.
down The interface was "discovered" by the
LLC2 driver, has passed its bootup
diagnostics, and is awaiting initial‐
ization.
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 diagnos‐
tics.
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
Interface
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 parameters associ‐
ated 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 anything.
