The following example uses the
dir bootflash:
command in privileged EXEC mode to learn the name of the
system image file and the
copy bootflash: tftp:
command in privileged EXEC mode to copy the system image
to a TFTP server. The router uses the default username and password.

Using TFTP or Remote Copy Protocol to Copy the System Image
into Boot Flash Memory
The following details the logistics of upgrading the system image:
Install a TFTP server or an RCP server application on a TCP/IP-ready workstation or PC. Many third-party
vendors provide free TFTP server software, which you can find by searching for
“
TFTP server
”
in a web
search engine.
If you use TFTP:
•
Configure the TFTP application to operate as a TFTP server, not a TFTP client.
•
Specify the outbound file directory to which you will download and store the system image.
•
Download the new Cisco IOS software image into the workstation or PC.
•
Verify that the TFTP or RCP server has IP connectivity to the router. If you cannot successfully ping
between the TFTP or RCP server and the router, either configure a default gateway on the router or
make sure that the router and server each have an IP address in the same network or subnet.
