The integrated LES/BUS is started. The LEC in the IBM 8285
automatically registers with it.

The ports attached the LECs are enabled. They are now ready to
connect ATM devices. Note that many LECs should be started after
the LES/BUS has been up because they have retry counts which limit
how many times they may issue the LANE registration request.
7.2.4 Troubleshooting Your LANE Network
There are relatively few entries in a LANE network that could cause you
problems. The following sections describe the typical items that should be
considered:
• Check the Physical (ATM) Connection
• Check the LANE Registration
• Other Considerations
For more information about troubleshooting your LANE network, refer to the
troubleshooting chapter of
IBM 8285 Nways ATM Workgroup Switch: Installation
and User

s Guide.
7.2.4.1 Check the Physical (ATM) Connection
When you connect an ATM device to the IBM 8285, you have to connect the
physical cabling to the device and configure its ATM parameters. Then the
device should be connected to the ATM network and you can check the status
from the IBM 8285 console using SHOW PORT command.
Figure 45 on page 140 shows a sample console screen when the commands
issued.
