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.

Within each DLMI are one or more 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

you connection is properly configured, you will automatically see a listing of the valid DLCIs on your link.

1. From the main Frame Relay window (see figure 70 on page 172), select

DLCI

to configure the PVCs.

Figure 130. DLMI—Configuration View window

An example Frame Relay connection with the management DLCI and one PVC with the DLCI of 100 is

shown in

figure 130. DLCI 100 has been configured by the Frame Relay service provider as the data link

the provider will use for transporting your data

2. To configure a DLCI you will need the IP address of the far-end router and the DLCI number if the DLCI

did not automatically appear. If the DLCI automatically appeared, enter the IP address of the far-end

router in the IP address field. Often, this will be the Ethernet address or loopback address for that router.

3. Select

Submit

If the DLCI did not automatically appear, do the following:

1. Under the DLCI entry, type the DLCI number given to you by your provider. Your DLCI identification

must match that provided by your service provider or the frame relay link will not function properly.

2. Under the IP Address entry, type the IP address of the far-end router. This will be the next-hop router for

this DLCI. Often, this will be the Ethernet address or loopback address for that router.

3. Click on
