Cisco PIX Firewall and VPN Configuration Guide

78-15033-01

Chapter 1 Getting Started

Using the Command-Line Interface

Step 5 The following prompt appears:

Password:

Press the Enter key.

Step 6 You are now in privilege Level 15, which lets you use all the commands assigned to this privilege level.

The following prompt appears:

pixfirewall#

Type configure terminal and press Enter. You are now in configuration mode.

Note If the Command Authorization feature (introduced in PIX Firewall Version 6.2) is enabled, the

commands you are permitted to enter are determined by the administrative privilege level to which your

user account has been assigned. For information about configuring this feature, refer to the “

Connecting

to PIX Firewall Over a VPN Tunnel” section in Chapter 9, “Accessing and Monitoring PIX Firewall.”

Abbreviating Commands

You can abbreviate most commands down to the fewest unique characters for a command; for example,

you can enter

wr t to view the configuration instead of entering the full command write terminal, or

you can enter

en to start privileged mode and con te to start configuration mode. In addition, you can

enter

0 to represent 0.0.0.0.

Backing Up Your PIX Firewall Configuration

You should back up your configuration in at least one of the following ways:

• Store the configuration in Flash memory with the write memory command. Should the need arise,

you can restore a configuration from Flash memory using the configure memory command.

• Use the write terminal command to list the configuration. Then cut and paste the configuration into

a text file. Then archive the text file. You can restore a configuration from a text file using the

configure terminal command and pasting the configuration either line by line or as a whole.

• Store the configuration on another system using the tftp-server command to initially specify a host

and the write net command to store the configuration.

• If you have a PIX 520 or older model, store the configuration on a diskette using the write floppy

command. If you are using Windows, make sure the diskette is IBM formatted. If you are formatting

a disk, access the MS-DOS command prompt and use the format command. Do not back up your

configuration to the PIX

Firewall boot disk.

Each image you store overwrites the last stored image.

Should the need arise, you can restore your configuration from Flash memory with the configure

memory command, or from diskette with the configure floppy command.
