DLCI window
“look” like a Frame Relay Network. By setting the LMI Interface to NETWORK, you can connect another
Frame Device directly to the access server. This is also the setting if you were to connect two access servers
back-to-back without the benefit of an established Frame Relay network.
Bidirectional Polling
Bidirectional Polling pertains only to the Network LMI side. If enabled, the Network LMI issues STATUS
ENQUIRY messages and waits for a STATUS reply from the User.
Polling Verification (T392)
Polling Verification pertains only to the Network LMI side. It is the amount of time permitted without receiv-
ing a STATUS ENQUIRY message from the User before Counting an Error.
Configuring Permanent Virtual Circuits
The Data Link Connection Identifier (DLCI) provides each PVC with a unique identifier at both the access
server and the Frame Relay switch. Within each link (DLMI) there can be multiple Permanent Virtual Circuits
(PVC). Each of these PVCs are point-to-point links to remote locations, and define the data path between the
access server and the Frame Relay network.
DLCI window
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 access server and the Frame Relay network switch.
This management channel communicates configuration and health information of the Frame Relay link. If
your Frame Relay service provider has properly configured your connection, you will automatically see a listing
of the valid DLCIs on your link.
