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 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.

–ippa

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 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.

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 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 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 anything.

Files

/etc/llc2/default/llc2.*

LLC2 configuration files
