For the examples of configuring the LAPB T1 timer, refer to "typical LAPB configuration examples".
5.5.2 X.25 configuration task list
To configure X.25, complete the tasks in one or more of the following sections, depending upon the
X.25 application or task required for your network. The interface, datagram transport, and routing tasks
are divided into sections based generally on how common the feature is and how often it is used. Those
features and parameters that are relatively uncommon are found in the "Additional" sections. LAPB
frame parameters can be modified to optimize X.25 operation, as described earlier in this chapter.
Default parameters are provided for X.25 operation; however, you can change the settings to meet the
needs of your X.25 network or as defined by your X.25 service supplier. D-LINK also provides
additional configuration settings to optimize your X.25 usage.
Note:
If you connect a router to an X.25 network, use the parameters set by your network administrator for the connection; these
parameters will typically be those described in the "Configure an X.25 Interface" and "Modify LAPB Protocol Parameters"
sections. Also, note that the X.25 Level 2 parameters described in the "Modify LAPB Protocol Parameters" section affect
X.25 Level 3 operations.
See the end of this chapter for examples of configuring the X.25.
5.5.3 Configure an X.25 interface
To configure an X.25 interface, perform the tasks in the following sections:
♦ encapsulate the X.25
♦ set the X.25 mode
♦ set the virtual circuit ranges
♦ set the X.121 address
♦ set the default flow control values
These tasks describe the parameters that are essential for correct X.25 behavior. The first task is
required. The others might be required or optional, depending on what the router is expected to do and
on the X.25 network.
5.5.4 encapsulating the X.25 protocol
User must encapsulate the X.25 protocol in the interface configuration mode before configuring the
X.25.
