Thanks for you reply.

1) I can use the port of management to make the upgrade of the IOS, and how ?

Or I have to make a configuration.

2) And On a switch 2950, I could stop the services:

- setup express

- exception memory ignore overflow io

- exception memory ignore overflow processor

but on one 3650, I do not know if is deactivated by default.

Anybody knows ?

Thanks,

Christopher.

Not sure what are asking here.

1) I can use the port of management to make the upgrade of the IOS, and how ?

What switch model are you referring to?

if this is a 3650, as I said on my first post use the USB port.

2) And On a switch 2950, I could stop the services:

no sure what your asking

Configuration file and the IOS image are 2 different things.

You don't need to stop any services when upgrading IOS.

All right for the question 1), thank you. So the upgrade by the USB is better that "install software" process. I had understood the opposite.

Thanks,

Christopher.

You should definitely use the "software install" command for this platform, but you can install it from the USB memory stick instead of TFTP if you like.

Ok,

Thanks You.

You really should use the "software install" process on this platform rather than change the boot environment variable.  The platform is modular, and you may not upgrade everything using that approach.

Thanks for you reply,

With which command, I can "Copy and paste from USB to flash, change the boot variable on the switch to make sure the new image will load after the reboot" please.

Thanks,

Christopher

Chris,

Use this command:

copy usbflash0 flash:<name of the file or image>

Make sure that the USB you are using is actually compatible with the switch, as not all USBs work with Cisco switches/routers. 

And the way you test the USB is by inserting it into the switch and than try reading one of the files on it.

Good Luck

Thank you Reza Sharifi.

Once copy and paste completed, than try this:

config t

boot system flash:<name of the ios>

exit

wr

reload.

It takes about 5 to 7 min for the switch to reboot with the new image.
