When would you need this:
When you are planning to upgrade the IOS file or you need to copy it to another
router.
Special Requirements: None.
Before starting the procedure
of IOS file backup, you will need to install TFTP server software on a PC
connected to the router Ethernet interface. There are many free downloadable
TFTP servers’ software on the Internet, however, our recommendation is Free
TFTP Server 6.0.
Afterwards, you make sure to
direct the TFTP server to the folder that you want to contain the backups, and
that the TFTP server has enough free space to contain the backups.
1. Create a console
connection with the default settings (9600 baud, 8 databits, 0 parity bits, 1
stop bit, no flow control).
2. Check the connectivity
between the router and the TFTP server with the ‘ping’ command.
3. Start copying the IOS file
with one of the following command:
Router#copy flash tftp
Use this command if your
router has internal flash memory (ex: 2600). If your router uses PCMCIA flash
cards (ex: 3600), use the following command:
Router#copy slot1: tftp >>> or Slot0: depending on the file you want to copy
4. Now you will be asked for
the IP address of the TFTP server:
Address or name of remote
host []? XXX.XXX.XXX.XXX
Afterwards, you will be asked
for a destination file name to be saved on the TFTP server
Destination filename [cXXXX-X-XX.XXX-XX.bin]?
It is better to leave the IOS
file name as it is so you would not be confused when you want to restore it.
Now you will see the progress
of the files transfer
