Hi Mahesh,

The "archive download-sw /overwrite /force-reload" is usually used when the switches are stacked. You apply this command and all the switches in the stack will be upgraded and when the upgrade is done, the stack will be also reloaded.

Basically, this is an automation command, so you don't have to go to every single switch to upgrade them. You just use this command. But if you switches are not stacked, then you can use the .bin command.

should we config the boot system flash: command or system automatically boots with new Image?

I my case i config the boot system flash: and switch rebooted with new ios in flash.

If you have multiple IOS images on the flash (like in your case) you want to add the boot system command so it boots from the IOS you want, if not it will load the first IOS on the flash. If your system is already booted with the new image, then you can simply delete all the old IOS image and free up the flash.

Hi Mahesh,

You can just copy the file from the TFTP server into the switch and then set your boot variable and reboot the switch.

copy tftp flash:

Or you can try using the "archive download-sw tftp...... to load the file to the switch.

Please be aware that .tar file is usually used when the switches are stacked. and .bin is used when the switches are not stacked.

Hi Reza,

i tried command

archive download-sw /leave-old-sw tftp://x.x.x.x//temp1/Images/c3750-ipserviceslmk9-tar.122-55.SE7.tar

IOS is on unix server and folder is temp1/Images/c3750-ipserviceslmk9-tar.122-55.SE7.tar

where x.x.x.x is IP of unix box

5//temp1/Images/c3750-ipserviceslmk9-tar.122-55.SE7.tar

Could not buffer tarfile...using multiple downloads

examining image...

%Error opening tftp://172.16.3.5//temp1/Images/c3750-ipserviceslmk9-tar.122-55.SE7.tar (Timed out)

Hi Mahesh,

Can you just try "copy tftp: flash .....

Reza

mahesh18 · ‎02-05-2013

Hi Reza,

I tried

copy tftp flash:

Address or name of remote host []? x.x.x.x

Source filename []? c3750-ipserviceslmk9-tar.122-55.SE7.tar

Destination filename [c3750-ipserviceslmk9-tar.122-55.SE7.tar]?

Hi Reza,

My bad i came to know Unix box only supports FTP and i was able to upgrade the IOS using FTP.

Need to confirm when we use the command

archive download-sw /overwrite /force-reload

should we config the boot system flash: command or system automatically boots with new Image?

I my case i config the boot system flash: and switch rebooted with new ios in flash.

Thanks

Hi Reza,

Many thanks for detailed explanation.

Today learned upgrading IOS with FTP.

I only did upgrade to single switch not stack and i used tar image

Hi Mahesh,

You are very welcome.

I should have mentioned that although tar file is usually for stacked switches, but it also works on non-stacked switches.

Please be aware if you are using 3750X series switches, Cisco has made our life a little easier by adding a USB port to the back of the switch. So, all you have to do is to insert a USB in your laptop/PC, copy the IOS from your PC to it and then insert the USB into the switch and copy the IOS image from the USB to flash and reboot. No more need for FTP, TFTP, etc...

The only issue I have seen is not all USB flash drives work with Cisco switches, but most do.
