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_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.

NAME

     ng_vlan -- IEEE 802.1Q VLAN tagging netgraph node type

SYNOPSIS

     #include <sys/types.h>
     #include <netgraph.h>
     #include <netgraph/ng_vlan.h>

DESCRIPTION

     The vlan node type multiplexes frames tagged according to the IEEE 802.1Q standard between different hooks.

     Each node has two special hooks, downstream and nomatch, and an arbitrary number of ``vlan'' hooks, each associated with a particular VLAN
     tag.

     An ETHERTYPE_VLAN frame received on the downstream hook with a tag that the node has been configured to filter is sent out the corresponding
     ``vlan'' hook.  If it does not match any of the configured tags, or is not of a type ETHERTYPE_VLAN, it is sent out the nomatch hook.  If the
     nomatch hook is not connected, the packet is dropped.

     An Ethernet frame received on the nomatch hook is passed unmodified to the downstream hook.

     An Ethernet frame received on any of the ``vlan'' hooks is tagged accordingly and sent out the downstream hook.

HOOKS

     This node type supports the following hooks:

     downstream  Typically this hook would be connected to a ng_ether(4) node, using the lower hook.

     nomatch	 Typically this hook would also be connected to an ng_ether(4) type node using the upper hook.

     <any valid name>
		 Any other hook name will be accepted and should later be associated with a particular tag.  Typically this hook would be attached
		 to an ng_eiface(4) type node using the ether hook.

CONTROL MESSAGES

     This node type supports the generic control messages, plus the following:

     NGM_VLAN_ADD_FILTER (addfilter)
	     Associates a hook with the tag.

     NGM_VLAN_DEL_FILTER (delfilter)
	     Disassociates a hook from the tag.

     NGM_VLAN_GET_TABLE (gettable)
	     Returns a table of all hook/tag associations.

EXAMPLES

     #!/bin/sh

     ETHER_IF=rl0

     ngctl -f- <<EOF
     shutdown ${ETHER_IF}:
     mkpeer ${ETHER_IF}: vlan lower downstream
     name ${ETHER_IF}:lower vlan
     connect ${ETHER_IF}: vlan: upper nomatch
     EOF

     ngctl mkpeer vlan: eiface vlan123 ether
     ngctl msg vlan: addfilter '{ vlan=123 hook="vlan123" }'

SHUTDOWN

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