Models 2616RC, 3096RC & 3196RC Admin Reference Guide 8 • Frame Relay
Within each DLMI are one or more Data Link Channel Identifier (DLCIs). This is the identification of a PVC
within the Frame Relay link.
There will be at least one PVC automatically installed. This is the management DLCI or LMI. This DLCI,
often DLCI 0, is the communication channel between the T-DAC and the Frame Relay network switch. This
management channel communicates configuration and health information of the Frame Relay link. See
figure 38.

DLCI (frCircuitDlci)
The Data Link Connection Identifier (DLCI) for this virtual circuit.
Note
DLCIs can automatically appear if your Frame Relay Service provider
has already configured your link. In this case, all you will need to
enter is the IP address of the router at the far end of the link.
Interface # (FrameIPInterfaceNum)
The interface number assigned to a DLCI. This is a variable number which is assigned from a resource pool
within the T-DAC.
State (frCircuitState)
This is the state of the interface with the following definitions:
• invalid(1)—Use this setting to delete DLCI’s on your T-DAC’s configuration view. To delete a DLCI, sim-
ply set the state to invalid(1) and Submit Query. Note: A deleted DLCI will reappear if your service pro-
vider’s Frame Relay switch is still configured to recognize that DLCI. This occurs after a Frame Relay Full
Status Enquiry.
• active(2)—The link is up and passing data. This is the desired condition of the link.
• invalid(3)—The link is down and not passing data. Reasons for this may be your service provider hasn’t
enabled your service or the link is not yet connected to your T-DAC.
