CIsco 4500 switch upgrade

[Dave Kozlowski]

Will upgrading my cisco switch overwrite my startup config?  And if so how can I save it?

Thanks

Dave

Hi, IOS firmware is a bin file saved in flash memory separated by startup-config saved in nvram.

So you can upgrade the IOS whitout loosing your config.

If you want you can save the configuration file exporting the "show run" in a text file or using external server and copy command.

E.g.

copy startup-config http

copy startup-config ftp

copy startup-config tftp
