Software Download through TFTP Server
This section contains instructions for downloading device software (system and boot images) through a TFTP
server. The TFTP server must be configured before beginning to download the software. This section contains the
following topics:
•
System Image Download
•
Boot Image Download
System Image Download
The device boots and runs when decompressing the system image from the flash memory area where a copy of
the system image is stored. When a new image is downloaded, it is saved in the area allocated for the other
system image copy.
On the next boot, the device decompresses and runs the currently active system image unless otherwise directed.
To download a system image through the TFTP server:
1. Ensure that an IP address is configured on one of the device ports and pings can be sent to the TFTP server.
2. Make sure that the file to be downloaded is saved on the TFTP server (the arc file).
3. Enter show version to verify which software version is currently running on the device. The following is an
example of the information that appears:
console# show version
SW version 1.0.0.42 (date 22-Jul-2004 time 13:42:41)
Boot version 1.0.0.18 (date 01-Jun-2004 time 15:12:20)
HW version
4. Enter show bootvar to verify which system image is currently active. The following is an example of the
information that appears:
console# sh bootvar
Images currently available on the Flash
Image-1 active (selected for next boot)
Image-2 not active
console#
5. Enter
copy tftp://{tftp address}/{file name} image
to copy a new system image to the
device. When the new image is downloaded, it is saved in the area allocated for the other copy of system
image (image-2, as given in the example). The following is an example of the information that appears:
console# copy tftp://176.215.31.3/file1.ros image
