How to Copy IOS From One Cisco Router to Another

Posted by bfindarto on March 12, 2008

Well.. there will be the time that you want to install an ios for your router (maybe becouse of your router’s ios is crashed) or you want to upgrade your ios… but… you dont’t have the tftp server around, then you guys can follow these steps.

This method will work with requirements: the flash size of the destination router should be adequate for the new IOS file size.

Okay… here’s how to do it:

On the source router that contains the IOS file that you want to copy, issue the following command:

Router(config)#tftp-server flash:/SOURCE-IOS-FILE.bin

Where SOURCE-IOS-FILE.bin is the name of the IOS file that you want to copy. If you are using a router that has PCMCIA flash card, replace the ‘flash:’ with ‘slot0:’ or ‘slot1:’ in the previous command, depending on the slot that contains the file that you want to copy.

This command will make the router act as a TFTP server. And the rest of the procedure is done on the target router and can be found on this link.

After you complete the copy operation, issue the command:

Router(config)#no tftp-server flash:/SOURCE-IOS-FILE.bin
