Configuring the X.25 Link
Chapter 3 49
Step 4. Click on OK to complete X.25 software configuration and save your
changes. Your X.25 interface (port) should appear in the object list with
status Enabled (no problem found and link connected correctly). If not,
carefully repeat the steps in this chapter until the configuration is
enabled.
If your port is not connected to a running network, it will display as
configured.
You have completed the interface configuration.
Step 5. Select Exit from the File menu if you have no need to configure access
to other systems or to PAD services. Then exit SAM.
If you need to configure access to other systems or configure PAD
services, stay in SAM and continue with the instructions in “Configuring
Remote System Access” (to configure access to other systems) and in
“Configuring PAD Services” (to configure PAD services).
NOTE Your system will not reboot when you exit. Your configuration is effective
immediately without the need to create a new kernel.
If you want to control Services (Internet/Berkeley Services or Network
Services (NS)), refer to the documentation set for those products.
Using Maximum Window-Size Settings with Modulo-128
When you configure Level 2 Modulo-128 parameters, we recommend that
you adjust the maximum window size values because of memory
allocation restrictions on the following cards:
• J3526A PCI 4-port card
Using window sizes higher than the recommended values could result in
periodic Level 2 resets and retransmission of packets.
The maximum window size that you can set depends on the packet size
you set for Level 3. For example, if you set a packet size of 4096 in Level
3, use a maximum Level 2 window size range of 1- 30.
If you set a packet size of 128, you can use a window-size between 1 and
127 (the maximum).
