The copy tftp flash command enables you to download a software image into the Flash memory of the firewall via TFTP. You can use the copy tftp flash command with any PIX Firewall model running Version 5.1 or higher.
The image you download is made available to the PIX Firewall on the next reload (reboot).
If the command is used without the location or pathname optional parameters, then the location and filename are obtained from the user interactively via a series of questions similar to those presented by Cisco IOS software. If you only enter a colon ), parameters are taken from the tftp-server command settings. If other optional parameters are supplied, then these values would be used in place of the corresponding tftp-server command setting. Supplying any of the optional parameters, such as a colon and anything after it, causes the command to run without prompting for user input.
The location is either an IP address or a name that resolves to an IP address via the PIX Firewall naming resolution mechanism (currently static mappings via the name and names commands). PIX Firewall must know how to reach this location via its routing table information. This information is determined by the ip address command, the route command, or also RIP, depending upon your configuration.
The pathname can include any directory names besides the actual last component of the path to the file on the server. The pathname cannot contain spaces. If a directory name has spaces, set the directory in the TFTP server instead of in the copy tftp flash command.
If your TFTP server has been configured to point to a directory on the system from which you are downloading the image, you need only use the IP address of the system and the image filename.
The TFTP server receives the command and determines the actual file location from its root directory information. The server then downloads the TFTP image to the PIX Firewall.
