Setting the Data Link
The data link defines the protocol you are using to send data packets over the
network. Define the data link between the router you are configuring and each serial
interface. The example in Figure 20 on page 366 configures 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
Configuring the IP Interface
In Figure 20 on page 366, the IP interface is PPP; enter network 3 at the Config>
prompt to configure this PPP interface:
Config>network 3
PPP interface configuration
Note: This procedure does not include details about the configuration of PPP. For
details, refer to
Software User’s Guide
Configuring X.25
Before configuring XTP, configure the X.25 parameters for each interface. The
following example configures the basic parameters for X.25 and is based on the
topology in Figure 20 on page 366.
The parameters you need to configure 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 configure
Interface 1
on the concentrator router as
defined 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 define 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
