Download File to Controller

Use COMMANDS > Download File to navigate to this page.

Use this page to download and install new controller Operating System software (code), a signature file

or a configuration file to your controller from a local TFTP (trivial file transfer protocol) server.

Note The TFTP server cannot run on the same computer as the Cisco WCS, because the Cisco WCS and the

TFTP server use the same communication port.

To download a file to the controller, perform these steps:

Step 1 From the File Type drop-down list, select the kind of file (Code, Configuration, or Signature file) you

want to download.

Step 2 Enter the configuration file encryption key that enables the data in the file to be encrypted when the file

is downloaded.

Step 3 Configure the IP address of the TFTP server, the Maximum Retries, the Timeout (in seconds), the

directory path on the server (default = /), and the name of the file to be transferred.

Step 4 Click the Download button.

The Cisco WCS downloads and installs the new controller Operating System software. This process

takes at least three minutes and overwrites your existing code and configuration.

Note You must reboot the controller after the new Operating System software is installed.
