SYNOPSIS


.In netgraph/ng_frame_relay.h

DESCRIPTION

The frame_relay node type performs encapsulation, de-encapsulation, and multiplexing of packets using the frame relay protocol. It supports up to 1024 DLCI’s. The LMI protocol is handled by a separate node type (see ng_lmi(4)).

The downstream hook should be connected to the synchronous line, i.e., the switch. Then hooks dlci0, dlci1, through dlci1023 are available to connect to each of the DLCI channels.

HOOKS

This node type supports the following hooks:

downstream
The connection to the synchronous line.
dlciX Here X is a decimal number from 0 to 1023. This hook corresponds to the DLCI X frame relay virtual channel.

CONTROL MESSAGES

This node type supports only the generic control messages.

SHUTDOWN

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