IBM SC30-3681-08 manual Using Sdlc Interfaces, Conguring Switched Sdlc Call-In Interfaces, 537

Chapter 37. Using SDLC Interfaces

This chapter how to use the SDLC interface and includes the following sections:

vªBasic Con®guration Procedureº

vªCon®guring Switched SDLC Call-In Interfacesº

vªSDLC Con®guration Requirementsº on page 538

You enter SDLC con®guration commands at theSDLC # Config> prompt, where # identi®es the interface you specify with the network command. Changes made to the routers con®guration do not take effect immediately, but become part of the router's static con®guration memory when it is restarted.

Basic Con®guration Procedure

This section outlines the minimum con®guration required for SDLC to be usable by DLSw or by APPN.

Before beginning any con®guration procedure, use thelist device command from the con®g process to list the interface numbers of different devices. At the con®g prompt, select the interface you want to con®gure by entering either:network interface number or n interface number. If you need any further con®guration command explanations, refer to the con®guration commands described in this chapter.

Con®guring Switched SDLC Call-In Interfaces

A switched SDLC call-in interface allows a PU type 2.0 device to dial into a 2210 using a switched SDLC line, providing an additional connectivity option to your network. The interface is restricted to PU type 2.0 devices and can run DLSw only.

Note: You cannot con®gure APPN over a switched SDLC call-in interface.

To con®gure a switched SDLC call-in interface:

1. Con®gure a V.25bis base network:

Config> set data-link v25bis 2 Config> net 2

V25bis Config>

(configure the V25bis net)

See ªChapter 41. Using the V.25bis Network Interfaceº on page 579 for more information about con®guring V25bis.

Note: Any physical layer parameters such as the encoding type and full vs. half duplex are con®gured on the V.25bis interface and not on the Switched SDLC dial circuit interface.

2. Add a dial circuit device:

Config> add device dial

3.Set the data link for the dial circuit interface to SDLC. In this example, the dial circuit is interface 3.

Config> set data-link sdlc 3

4. Con®gure the dial circuit:
