TFTP Software Download

This section discusses the following:

Using the Configurator web pages or the CLI, you can download software or restore configuration data from a TFTP server. To do so, you must have a viable IP network connection between the Passport 4400 and the TFTP host machine containing the application code or configuration files. For information on configuring a Passport 4400 for IP services, see Configuring LAN Services.

To download a new version of system software to a Passport 4400, you must perform two separate download procedures:

download the boot image
download the application code.

Note that there is only one bank of boot code in the Passport 4400 Flash memory, but there are two different banks that may contain application code. Therefore, when downloading an application code, it is necessary to tell the Passport 4400 which bank should receive the new code. See "Working with Flash Memory Banks" on page 1-8 for more information.

There are two methods that can be used to accomplish a TFTP download:

Default Download Procedure -- Set the source and target IP addresses and download filename before invoking the download command, then execute the following CLI command:

CLI> download base image default command

Specific Download Procedure -- Execute the CLI command:

CLI> download base image specific

Set the parameters one by one "on the fly."

Note: You can download only one software image to the Passport 4400 at a time. It is possible to download the same software to multiple Passport 4400 units at the same time.
