Appendix D Troubleshooting and SunATM Error Messages 105
▼ To Diagnose LAN Emulation Configuration
Problems
1. Check all of the generic configuration points.
These are issues that apply to all SunATM interfaces, so they must all be working in
order for LAN Emulation to work.
2. Verify the output of ifconfig(1M).
Executing the command ifconfig -a should display the ATM LAN Emulation
interface, laneN, where N is the instance number.
■ If your interface does not appear, an error probably occurred during the boot
process.
Check for error messages during the boot process. The meanings and possible
solutions for error messages can be found in “Error Messages” on page 110.
■ If your interface appears, but has incorrect information, verify your configuration
files.
The information given to ifconfig comes from the /etc/opt/SUNWconn/atm/
atmconfig and /etc/opt/SUNWconn/atm/laneconfig files. Check the
entries in those files that apply to this interface and verify their contents. For
descriptions of the file formats, see “Editing the atmconfig File” on page 42 and
“Editing the laneconfig File” on page 53, or the atmconfig(4) and
laneconfig(4) man pages.
3. Check the setup_state with lanestat(1M).
This command provides information about the LAN Emulation status on your
interface. The setup_state refers to the completion of the lanesetup program.
■ If the setup_state is setup-started:
This indicates that the lanesetup program has not completed; it may be delayed
by slow switch responses, or failed attempts to register ATM addresses in
/etc/opt/SUNWconn/atm/laneconfig. Make sure that the local address given
for your interface in /etc/opt/SUNWconn/atm/laneconfig is unique to this
switch. Using the variable $myaddress for all systems is a good way to
guarantee that all addresses are unique. After making any changes to /etc/opt/
SUNWconn/atm/laneconfig,runlanesetup again.
■ If the state is not setup-started or setup-finished:
Verify that the addresses and interfaces in /etc/opt/SUNWconn/atm/
laneconfig are valid, and rerun lanesetup. If you see any error messages,
check their meanings in “Error Messages” on page 110.
