NG_ATMLLC(4)	       FreeBSD Kernel Interfaces Manual		  NG_ATMLLC(4)

NAME
     ng_atmllc -- ATM LLC netgraph node	type

SYNOPSIS
     #include <netgraph/ng_atmllc.h>

DESCRIPTION
     The atmllc	node type translates frames in to and out of ATM LLC encapsu-
     lation, as	specified by RFC 1483.	In LLC encapsulation the protocol of a
     given protocol data unit (PDU) is specified by an IEEE 802.2 LLC header,
     possibly followed by an IEEE 802.1a SubNetwork Attachment Point (SNAP)
     header.  This node	currently handles the Ethernet and FDDI	protocols.

     The node transmits	and receives ATM PDUs on the atm hook.	Received PDUs
     are decoded and forwarded to the ether or fddi hooks as appropriate.
     Data received on the ether	or fddi	hooks are assumed to be	full Ethernet
     or	FDDI packets as	appropriate and	are encapsulated into a	PDU and	trans-
     mitted via	the atm	hook.

HOOKS
     This node type supports the following hooks:

     atm    ATM	connection.  Typically,	this hook would	be connected to	a
	    ng_atm(4) node, which handles transmission of ATM PDUs over	an ATM
	    device.

     ether  Ethernet connection.  This hook sends and receives Ethernet
	    frames.  This would	normally be connected to an ng_eiface(4) node
	    if in use.

     fddi   FDDI connection.  This hook	sends and receives FDDI	frames.

CONTROL	MESSAGES
     This node type supports the generic control messages.

SHUTDOWN
     This node shuts down upon receipt of a NGM_SHUTDOWN control message, or
     when all hooks have been disconnected.
