Upgrading a Switch by Using the CLI
This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a
TFTP server and extract the files. You can download an image file and replace or keep the current image.
To download software, follow these steps:
Step 1
Use
Step 2
Download the software image file. If you have a SmartNet support contract, go to this URL, and log in
to download the appropriate files:
http://www.cisco.com/kobayashi/sw-center/sw-lan.shtml
Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP
Step 3
server is properly configured.
For more information, see Appendix B in the software configuration guide for this release.
Log into the switch through the console port or a Telnet session.
Step 4
(Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC
Step 5
command:
Switch# ping tftp-server-address
For more information about assigning an IP address and default gateway to the switch, see the software
configuration guide for this release.
Download the image file from the TFTP server to the switch. If you are installing the same version of
Step 6
software that is currently on the switch, overwrite the current image by entering this privileged EXEC
command:
Switch# archive download-sw /overwrite /reload
tftp:[[//location]/directory]/image-name.tar
The /overwrite option overwrites the software image in flash memory with the downloaded one.
The /reload option reloads the system after downloading the image unless the configuration has been
changed and not saved.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory
and image names are case sensitive.
This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite
the image on the switch:
Switch# archive download-sw /overwrite tftp://198.30.20.19/cbs30x0lanbase-mz
You can also download the image file from the TFTP server to the switch and keep the current image by
replacing the /overwrite option with the /leave-old-sw option.
