Examples
The following examples show how to copy a startup configuration to a TFTP server and how to copy
from flash memory to an FTP server.
Copying the Startup Configuration to a TFTP Server: Example
The following example shows the startup configuration being copied to a TFTP server:
Router# copy nvram:startup-config tftp:
Remote host[]? 192.0.0.1
Name of configuration file to write [rtr2-confg]?
rtr2-config-b4upgrade
Write file rtr2-confg-b4upgrade on host 192.0.0.1?[confirm] <cr>
![OK]
Copying from Flash Memory to a TFTP Server: Example
The following example uses the dir flash: command in privileged EXEC mode to learn the name of the
system image file and the copy flash: tftp: command in privileged EXEC mode to copy the system
image (c2800-2is-mz) to a TFTP server. The router uses the default username and password.
Router# dir flash:
System flash directory:
File Length Name/status
1 4137888 c2800-image-mz
[4137952 bytes used, 12639264 available, 16777216 total]
16384K bytes of processor board System flash (Read/Write)\
Router# copy flash: tftp:
IP address of remote host [255.255.255.255]? 192.0.0.1
filename to write on tftp host? c2800-image-mz
