Lab Infrastructure
Equipment configuration
Equipment configuration (2)
Equipment configuration (3)
Access modes
The PIX firewalls (and other CISCO equipment) have
four administrative access modes:
Unprivileged mode: Available at first access. Provides a
restricted, limited view of system settings. (Prompt = ‘>’)
Privileged mode: Allows you to change system settings.
(Prompt = ‘#’)
Configuration mode: Enables you to change system
configurations. (Prompt = ‘(config)#’
Monitor mode: Special mode that allows you to update
system configuration image over the network (using a
TFTP server)
Access modes (2)
To access privilege mode
enable
To access configuration mode
configure terminal
Use the exit command to exit from one mode
to the previous one
Firewalls
System or group of systems that manage
access between two networks
DMZ
Internet
Router

Network
Firewall
Inside
Network
PIX Firewalls
Proprietary operating system
Stateful inspection
Protocol and application inspection
User-based authentication
Virtual private networking
Web-based management
Stateful failover capabilities
Graphical configuration environment
(PIX 501 Firewall)
Important: To access the GUI configuration
environment on the PIX 501 use a PC
connected to the PIX and a browser with the
MICROSOFT JAVA VM enabled !!
Activate GUI environment via browser
https://192.168.1.1/pdm.html
Viewing / Saving configurations
There are two configuration memories, running
configuration and startup-configuration
show running-config displays the current
configuration in the RAM memory of the equipment. Any
configuration changes are written to the runningconfiguration
write memory saves the current running-configuration
to the flash memory startup-configuration
show configure shows the configuration that is in flash
memory
show history displays previously entered commands
Cabling description
Networking ports for each computer are numbered
Correspondence (see picture)
Move the patch cords to where you need them if they
are not properly set.
Basic CISCO IOS commands
ip address if_name ip_address [netmask]
ip address ethernet2 172.16.0.1 255.255.255.0
show ip address
Displays the IP adresses assigned to all
interfaces
show interface
allows you to view the network interface
information and status
ping ip_address
To determine reachability of a system
Basic Windows/Linux networking
commands
ipconfig (windows) / ifconfig (linux)
To obtain ip configuration information of a PC
ping
netstat –r
To obtain routing configuration and statistics
netstat
Gives you information on active ports and
established connections on a system
Lab procedures
Lab assignments will be given a couple of days in
advance to the start of the lab working period
Lab working periods = 1 or 2 weeks
Lab groups should be composed of two persons (no
more, no less)
Use sign-up sheet to schedule the time in which you
will be using lab equipment
Lab reports can be written in any format but should
include answers to the questions presented in the
assignment and equipment configuration files
Important recommendations
Never change a password (you’ll be held
accountable) unless its for your own user
account
Discharge often – get rid of static electricity
build up before touching equipment
