Use the download command to copy a software image from a specified host to the Flash memory of a designated module.
download host file [mod_num]download serial [mod_num]
Syntax Description
| host | Name or IP address of host. |
| file | Name of file to be downloaded. |
| mod_num | (Optional) Number of the module to receive downloaded image. |
| serial | Keyword that specifies download through a serial port. |
Default
If a module number is not specified, the image is downloaded to all modules for which the image is valid.
Command Type
Switch command.
Command Mode
Privileged.
Usage Guidelines
The Catalyst 5000 series switches support two ways to download new code to the processors: TFTP network download through any network port, and Kermit serial download through the EIA/TIA-232 console port. Only the first applies to the ATM module. The ATM module has processors that will require field upgrades.
The download command downloads code to the module Flash memory. Catalyst 5000 series software rejects an image if it is not a valid image for the module.
When downloading to the ATM module, the supervisor module acts as a TFTP gateway, forwarding TFTP packets to the ATM module through an in-band IPC method.
To download a software image for the RSM, use the session command.
The download serial command uses the Kermit protocol through the serial EIA/TIA-232 console port. The download serial command is not allowed from a Telnet session.
This command is not supported by the three-port Gigabit Ethernet switching module (WS-X5403).
If the module number is specified, 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 the module number is not specified, the download goes to all modules of that type.
 |
After starting the serial download using Kermit, do not attempt to abort the serial download by using Ctrl-C. Pressing Ctrl-C interrupts the download process and could leave the switch in a problematic state. If this occurs, reboot the switch. |
