44 .Nd frame relay netgraph node type
46 .In netgraph/frame_relay/ng_frame_relay.h
50 node type performs encapsulation, de-encapsulation, and multiplexing
51 of packets using the frame relay protocol. It supports up to 1024 DLCI's.
52 The LMI protocol is handled by a separate node type (see
57 hook should be connected to the synchronous line, i.e., the switch.
63 are available to connect to each of the DLCI channels.
65 This node type supports the following hooks:
67 .Bl -tag -width foobar
69 The connection to the synchronous line.
71 Here X is a decimal number from 0 to 1023. This hook corresponds
72 to the DLCI X frame relay virtual channel.
75 This node type supports only the generic control messages.
77 This node shuts down upon receipt of a
79 control message, or when all hooks have been disconnected.
87 node type was implemented in
90 .An Julian Elischer Aq julian@FreeBSD.org
92 Technically, frames on DLCI X should not be transmitted to the switch
93 until the LMI protocol entity on both ends has configured DLCI X as active.
96 node type ignores this restriction, and will always pass data received
99 Instead, it should query the LMI node first.
