Chapter 37. Using SDLC Interfaces

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

v“Basic Conﬁguration Procedure”

v“Conﬁguring Switched SDLC Call-In Interfaces”

v“SDLC Conﬁguration Requirements” on page538

You enter SDLC conﬁguration commands at the SDLC # Config> prompt, where #

identiﬁes the interface you specify with the network command. Changes made to

the routers conﬁguration do not take effect immediately,but become part of the

router’s static conﬁguration memory when it is restarted.

Basic Conﬁguration Procedure

This section outlines the minimum conﬁguration required for SDLC to be usable by

DLSw or by APPN.

Before beginning any conﬁguration procedure, use the list device command from

the conﬁg process to list the interface numbers of different devices. At the conﬁg

prompt, select the interface you want to conﬁgure by entering either: network

interface number

or n

interface number

. If you need any further conﬁguration

command explanations, refer to the conﬁguration commands described in this

chapter.

Conﬁguring 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: Youcannot conﬁgure APPN over a switched SDLC call-in interface.

Toconﬁgure a switched SDLC call-in interface:

1. Conﬁgure a V.25bisbase network:

Config> set data-link v25bis 2

Config> net 2

V25bis Config>

(configure the V25bis net)

See “Chapter 41. Using the V.25bisNetwork Interface” on page 579 for more

information about conﬁguring V25bis.

Note: Any physical layer parameters such as the encoding type and full vs.

half duplex are conﬁgured on the V.25bisinterface 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. Conﬁgure the dial circuit:
