Hi

How do you change the config registers on a Cisco 3750G so that I can change the boot parameters to boot from a new image ?

Thanks

Hello Raj

These commands do not work on the 3750G I have, running IOS c3750-ipbase-mz.122-25.SEB4 ?

Re: Change Config Registers

The only set command on the switch is Set Memory Debug or set express. It does not provide me with any other options to configure boot parameters.

help !!!

Re: Change Config Registers

Hi,

there is the "boot system" global configuration command by which you can specify the IOS image to load. However when upgrading the switch via "archive download-sw" you normally do not need to use this command as the boot variable is set up automatically (you can check via "show boot" command.

Best regards,

Antonin
