download

Use the download command to copy a software image from a specified host to the Flash memory of a designated module.

Syntax Description

host	Name or IP address of host.
file	Name of file to be downloaded.
mod	(Optional) Number of the module to receive the downloaded image.
rcp	(Optional) Keyword to specify rcp protocol as the file transfer method.
serial	Keyword to specify download through a serial port.

Defaults

If a module number is not specified, the image is downloaded to all modules for which the image is valid.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

The Catalyst 6000 family switches download new code to the processors using Kermit serial download through the EIA/TIA-232 console port.

The download command downloads code to the module Flash memory. Catalyst 6000 family switch software rejects an image if it is not a valid image for the module.

The download serial command uses Kermit through the serial EIA/TIA-232 console port. The download serial command is not allowed from a Telnet session.

If you specify the module number, the download goes to the specified module, but the download will fail if the module is of a different type than is indicated by the download header. If you do not specify the module number, the download goes to all modules of that type.

Caution After starting the serial download using Kermit, do not attempt to abort the serial download by pressing Ctrl-C. Pressing Ctrl-C interrupts the download process and could leave the switch in a problematic state. If this occurs, reboot the switch.

Examples

This example shows how to download the c6000_spv11.bin file from the mercury host to the supervisor engine (by default):
