•
Obtain the IP address of the TFTP server in which the software file has been stored.
•
If VLANs are configured on the switch, determine the name of the VLAN in which the TFTP server is operating.
•
Determine the name of the software file stored in the TFTP server for the switch (For example, E0820.swi).
NOTE: If your TFTP server is a UNIX workstation, ensure that the case (upper or lower) that you
specify for the filename is the same case as the characters in the software filenames on the server.
Troubleshooting TFTP download failures
Cause
When using the menu interface, if a TFTP download fails, the Download OS (Operating System, or software)
screen indicates the failure as seen in the following figure.
Figure 35: Example: of message for download failure
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 (Operating System, or software) screen.
•
One or more of the switch's IP configuration parameters are incorrect.
•
For a UNIX TFTP server, the file permissions for the software file do not allow the file to be copied.
•
Another console session (through either a direct connection to a terminal device or through Telnet) was
already running when you started the session in which the download was attempted.
