Configuring Frame Relay
Frame Relay (FR) is a form of packet-switching, using smaller packets and less error checking
than traditional forms of packet switching. For every FR interface, you must configure a
dedicated line. You can obtain administrative information about the status of the FR interface
by defining link management frames, specifically assigning a unique Data Link Connection
Identifier (DLCI) address. By setting parameters for IP Routing, you can configure a gateway
for all incoming FR calls. You can configure the MAX as a FR switch so that the MAX can
receive frames on one interface and transmit them onto another interface. You can enable the
MAX to support a FR switched connection over ISDN BRI or PRI connections.
You can set all these configurations (except for the last) in either the Connection profiles or the
RADIUS profiles.
Introduction
In the Frame Relay network, every access point connects directly to a switch. Frame Relay
virtual circuits (VCs) are bidirectional data paths between two endpoints. An established
permanent virtual circuit (PVC) is a connection between two endpoints, which can include a
number of hops in between.
Depending on how a device such as the MAX is integrated into a Frame Relay network, it can
operate as a Frame Relay terminating unit (Customer Premise Equipment or CPE) or as a
Frame Relay switch.
A CPE is the source or destination of data traversing the Frame Relay service. For example, the
MAX labeled MAX-02 in Figure 5-1 terminates the data stream to its PPP callers. When it is
