Troubleshooting

A.1.5 Check Firmware

To check whether or not the firmware is running correctly, issue the following
command:

atmstat fa0 1

In this command, the last parameter “1”, causes the command to be repeated
at one-second intervals.

If the firmware is running correctly, the response will show Input, Output,
and Error Statistics for the adapter in the following format:

PHY/ATM/AAL statistics:

Output Input Errors

ATM AAL* ATM AAL* 4B5B 4B5B ATM AAL* AAL*

Cells CS-PDUs Cells CS-PDUs Framing Hdr-CRC VPI/VCI Pay-CRC Proto

161747 153692 142289 134685 0 0 20 0 0

If the firmware is not running correctly,

atmstat

hangs and nothing is

returned, indicating either a problem with the firmware, a problem with the
board, or a severe software failure. Call Cabletron Systems’ Technical Support
for further assistance.

If the output shows zeros for all possible values, the firmware may not have
been initialized. Try rebooting the system. If there is still a problem, call
Cabletron Systems’ Technical Support for further assistance.
