Installing and Recovering PIX Firewall Software

This section contains the following topics:

• Installing Image Software from the Command Line

• Using Monitor Mode to Recover the PIX Firewall Image

• Using Boothelper

• Downloading an Image with Boothelper

Installing Image Software from the Command Line

To use TFTP to install a software image from the PIX Firewall command line, enter the following

command:

copy tftp flash

You can use this command with any PIX Firewall running Version 5.1 or higher. When you enter this

command, the PIX Firewall prompts for the specific values required to complete the operation. You can

also use a colon (:) to take the parameters from the tftp-command settings, or you can explicitly specify

each parameter. For details, refer to the copy tftp flash command in the Cisco PIX Firewall Command

Reference.

Caution Never download a PIX Firewall image earlier than Version 4.4 with TFTP. Doing so will corrupt the

PIX Firewall Flash memory unit.

Using Monitor Mode to Recover the PIX Firewall Image

You can use monitor mode to recover the PIX Firewall image when it has been lost or corrupted and you

do not have access to the PIX Firewall command line.

Note You must use a 1FE or 4FE card installed in a 32-bit slot for installing image software with monitor

mode. You cannot use monitor mode to connect to a TFTP server through a Gigabit Ethernet card, a

4FE-66 card, or a Fast Ethernet card installed in a 64-bit slot.

Perform the following steps to download an image over TFTP using monitor mode:

Step 1 Immediately after you power on the PIX Firewall and the startup messages appear, send a BREAK

character or press the Esc (Escape) key.

The monitor> prompt appears.

Step 2 If desired, enter a question mark (?) to list the available commands.

Step 3 Use the address command to specify the IP address of the PIX Firewall unit’s interface on which the

TFTP server resides.

Step 4 Use the server command to specify the IP address of the host running the TFTP server.

Step 5 Use the file command to specify the filename of the PIX Firewall image. In UNIX, the file needs to be

world readable for the TFTP server to access it.
