    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 encapsulation, 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 transmitted via the atm hook.  

    HOOKS

    This node type supports the following hooks:

    atm
    ATM connection. Typically, this hook would be connected to a ng_atm4 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_eiface4 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.
