Hello,

 

I somewhere seem to remember that you cannot set the configuration register from rommon. At the rommon: prompt, boot the switch using the 'boot' command, and once it is booted, set the value (config-register 0x2141)...

Hi,

When in the rommon and after "confreg" can you please answer the last question:

change the boot characteristics? y/n [n]: y

and when prompted:

enter to boot:

0 = ROM Monitor

1 = the boot helper image

2-15 = boot system

[0]:

just input 2, ie:

[0]: 2

then save & reset.

Best regards,

Antonin

Wait ... This doesn't make any sense.
If the switch can boot into ROMMON, what is the reason behind entering "0x2142"?
