TFTP Recovery - Breaking into the BootROM

Unsuccessful downloading as a result of a corrupted file, premature time-out, etc., may cause the switch to enter a reboot "loop". If this happens, do the following:

1.Stop the loop situation and break into the BootROM menu by pressing the Enter key during the boot process. This stops the loop.

2.login and use the set of commands provided by the BootROM.

3.Use the set of commands provided by the BootROM to set or check the TFTP setting. You can check with the following commands:

∙get-sw-filegives you the software name,

∙get-tftp-srvrdisplays the tftp server IP address

∙get-tftp-modeprovides you with the mode (client or server)

To set the configuration use the commands below:

∙set-sw-file Filename (the name of the software located into the tftp server)

∙set-tftp-srvr(the tftp server's IP address)

∙set-tftp-mode client

4.At this point, you can use the previously entered TFTP parameters, and a new download session started with the sw-dnldcommand.

NOTE: After successful completion of the download, the switch reboots and operates the new firmware, but keeps the old parameters.
