Troubleshooting TFTP Downloads
If a TFTP download fails, the Download OS screen indicates the failure.
Figure A-4. Example of Message for Download Failure
To find more information on the cause of a download failure, examine the
messages in the switch’s Event Log by executing this CLI command:
SMC TigerSwitch 10/100# show log tftp
(For more on the Event Log, see “Using the Event Log To Identify Problem
Sources” on page 11-10.)
Some of the causes of download failures include:
■ Incorrect or unreachable address specified for the TFTP Server parameter.
This may include network problems.
■ Incorrect VLAN.
■ Incorrect name specified for the Remote File Name parameter, or the
specified file cannot be found on the TFTP server. This can also occur if
the TFTP server is a Unix machine and the case (upper or lower) for the
filename on the server does not match the case for the filename entered
for the Remote File Name parameter in the Download OS screen.
■ One or more of the switch’s IP configuration parameters are incorrect.
■ For a Unix TFTP server, the file permissions for the OS file do not allow
the file to be copied.
