Once booted, can you run "dir" and paste the output here?

Also, to change the boot file, issue the command syntax "set boot system flash device:<filename>"

So run the following command....

"set boot system flash bootflash:cat4000-k8.8-3-2-GLX.bin"

This should change your boot parameter and allow for autoboot. It appears you get the config from a TFTP server. So, you will then copy the config to your TFTP server so that upon reload, it gets the correct information. Or, you can modify the config on the TFTP server so that it boots correctly.

This did not work , maybe because then BOOT variable is full of trash ?

Add the following config line as well...

set boot auto-config bootflash:switch.cfg

If that is your actual config file.

rommon 3 > clear boot system all
Usage: clear boot
rommon 4 > set boot system flash bootflash:cat4000-k8.8-3-2-GLX.bin
Combined new BOOT variable would be too long!
Not changing BOOT variable in NVRAM.

These commands need to be run after the switch has booted. So issue the boot command and once in the CatOS, then issue the commands I provided earlier.

The switch is still not booting.
I don't know the name of my .cfg file

Console> (enable) clear boot system all
BOOT variable =
Console> (enable) set boot system flash bootflash:cat4000-k8.8-3-2-GLX.bin
BOOT variable = bootflash:cat4000-k8.8-3-2-GLX.bin,1;
Console> (enable) set boot auto-config bootflash:switch.cfg
CONFIG_FILE variable = bootflash:switch.cfg
Warning: File not found but still added in the auto-config string.
Console> (enable)

There may not be one. Have you done any other configurations on this switch?
