Note: New con®gurations do not take effect until you restart the router.

Setting the Data Link

The data link de®nes the protocol you are using to send data packets over the network. De®ne the data link between the router you are con®guring and each serial interface. The example in Figure 20 on page 366 con®gures a concentrator router with three serial interfaces, two for X.25 and one for PPP.

Set the data-link protocol for the serial interfaces:

Config>set data-link X25 1

Config>set data-link x25 2

Config>set data-link ppp 3

Con®guring the IP Interface

In Figure 20 on page 366, the IP interface is PPP; enter network 3 at the Config> prompt to con®gure this PPP interface:

Config>network 3

PPP interface configuration

Note: This procedure does not include details about the con®guration of PPP. For details, refer to Software User's Guide

Con®guring X.25

Before con®guring XTP, con®gure the X.25 parameters for each interface. The following example con®gures the basic parameters for X.25 and is based on the topology in Figure 20 on page 366.

The parameters you need to con®gure depend on your network topology. For details about all the X.25 parameters, refer to Software User's Guide

Interface 1

Use the following instructions to con®gureInterface 1 on the concentrator router as de®ned in Figure 20 on page 366.

1.At the Config> prompt, enter network followed by the number of the X.25 interface. In this example, it is interface 1.

Config>network 1

X.25 User Configuration

X.25 Config>

2.Add the XTP protocol to the X.25 interface and de®ne general interface values. Enter add protocol xtp at the X.25 Config> prompt. This command needs to be entered one time only.

X.25 Config>add protocol xtp

Window Size [2]?

Default Packet Size [128]?

Maximum Packet Size [256]?

3.Specify the network address by entering set address X.25 node address. In Figure 20 on page 366, the node address (DTE address) is 100.

X.25 Config>set address 100
