3-2 Frame Relay Module 4.0 User Guide, Rev 01Most parameters can be specified and/or changed using the operationsdescribed throughout the configuration portion of this manual; others, suchas RLP and port number, are defined by the hardware or specified duringsoftware installation.Configuration ExamplesLegacy Protocols over Frame Relay via Logical PortsBelow is a sample configuration and guidelines for configuring Logical Ports forAnnex G or RFC 1490 transmission over frame relay.Figure 3-1 Configuration Example 1Configure the following in each FRM:l RLP parameters (Chapter 5), to configure the RLP(s) that contain the ports overwhich the protocols will run. Each serial protocol (SNA, async, BSC, X.25,frame relay) must be configured on the RLP that contains the port.l Physical port (Chapter 6 plus Chapter 7 [Frame Relay], Chapter 8 [X.25],Chapter 9 [SNA], Chapter 10 [BSCI], and Chapter 12 [Async]).l Logical port (Chapter 8) on the physical frame relay port that connects to thenetwork. (Note that logical ports are numbered 8–63, because 0–7 are thephysical ports.)l SVC subscriber (Chapter 7 [Frame Relay], Chapter 8 [X.25], Chapter 9 [SNA],Chapter 10 [BSCI], and Chapter 12 [Async]), which assigns static addressesused to route the call request packets of the physical access ports to the logicalport and vice versa. Subscriber addresses are based on the X.121 Called Addressfield.l Optional SVC subscriber records (static routes) for any attached X.25 DTEs.These are needed to identify the attached DTEs’ X.121 Calling Addresses. If anX.25 Call Request is received from the WAN link, the FRM needs to knowwhere to route the call.SDLCAsyncBSCIX.25Sync passthruSDLCAsyncBSCIX.25Sync passthruFrameRelayFRM FRMLogical Ports
