Some of the instructions and examples provided in this manual contain CLI commands,
most of which perform initial configuration of the NetScreen-200 device. The command
examples use conventions for variables and syntax.
&/,&RPPDQG9DULDEOHV
Most NetScreen CLI commands have changeable parameters that affect the outcome of
command execution. NetScreen documention represents these parameters as variables.
Such variables may include names, identification numbers, IP addresses, subnet masks,
numbers, dates, and other values.

The variable notation used in this manual consists of italicized parameter identifiers. For
example, the set arp command uses four identifiers, as shown here:
set arp
{
ip_addr mac_addr interface
age number |
always-on-dest |
no-cache
}
where
•ip_addr represents an IP address.
•mac_addr represents a MAC address.
•interface represents a physical or logical interface.
•number represents a numerical value.
Thus, the command might take the following form:
ns-> set arp 172.16.10.11 00e02c000080 ethernet2
where 172.16.10.11 is an IP address, 00e02c000080 is a MAC address, and ethernet2 is
a physical interface.
&RPPRQ&/,9DULDEOH DPHV
The following list shows the CLI variable names used in NetScreen documents.
comm_name The community name of a host or other device.
date_str A date value.
dev_name A device name, as with flash card memory.
dom_name A domain name, such as “acme” in www.acme.com.
dst_addr A destination address, as with a policy definition that defines a source and
destination IP address.
filename The name of a file.
grp_name The name of a group, such as an address group or service group.
interface A physical or logical interface.
id_num An identification number.
ip_addr An IP address.
key_str A key, such as a session key, a private key, or a public key.
key_hex A key expressed as a hexadecimal number.
loc_str A location of a file or other resource.
mac_addr A MAC address.

Some commands contain multiple variables of the same type. The names of such variables
may be numbered to identify each individually. For example, the set dip command
contains two id_num variables, each numbered for easy identification:
set dip group id_num1 [ member id_num2 ]
&/,&RPPDQG6\QWD[
Each CLI command description in this manual reveals some aspect of command syntax.
This syntax may include options, switches, parameters, and other features. To illustrate
syntax rules, some command descriptions use dependency delimiters. Such delimiters
indicate which command features are mandatory, and in which contexts.
mbr_name The name of a member in a group, such as an address group or a service
group.
mask A subnet mask, such as 255.255.255.224 or /24.
name_str The name of an item, such as an address book entry.
number A numeric value, usually an integer, such as a threshold or a maximum.
pol_num A policy number.
port_num A number identifying a logical port.
pswd_str A password.
ptcl_num A number uniquely identifying a protocol, such as TCP, IP, or UDP.
serv_name The name of a server.
shar_secret A shared secret value.
spi_num A Security Parameters Index (SPI) number.
src_addr A source address, as with a policy definition that defines a source and
destination IP address.
string A character string, such as a comment.
svc_name The name of a service, such at HTTP or MAIL.
time_str A time value.
tunn_str The name of a tunnel, such as an L2TP tunnel.
url_str A URL, such as www.acme.com.
usr_str A user, usually an external entity such as a dialup user.
vrouter A local virtual router, such as trust-vr or untrust-vr.
zone The name of a security zone.

Each syntax description shows the dependencies between command features by using
special characters.
•The { and } symbols denote a mandatory feature. Features enclosed by these
symbols are essential for execution of the command.
•The [ and ] symbols denote an optional feature. Features enclosed by these
symbols are not essential for execution of the command, although omitting such
features might adversely affect the outcome.
•The | symbol denotes an “or” relationship between two features. When this
symbol appears between two features on the same line, you can use either
feature (but not both). When this symbol appears at the end of a line, you can
use the feature on that line, or the one below it.
HVWHG'HSHQGHQFLHV
Many CLI commands have nested dependencies, which make features optional in some
contexts, and mandatory in others. The three hypothetical features shown below
demonstrate this principle.
[ feature_1 { feature_2 | feature_3 } ]
In this example, the delimiters [ and ] surround the entire clause. Consequently, you can
omit feature_1, feature_2, and feature_3, and still execute the command successfully.
However, because the { and } delimiters surround feature_2 and feature_3, you must
include either feature_2 or feature_3 if you include feature_1. Otherwise, you cannot
successfully execute the command.
The following example shows some of the set interface command’s feature dependencies.
set interface vlan1 broadcast { flood | arp [ trace-route ] }
The { and } brackets indicate that specifyng either flood or arp is mandatory. Bycontrast,
the [ and ] brackets indicate that the arp option’s trace-route switch is not mandatory.
Thus, the command might take any of the following forms:
ns-> set interface vlan1 broadcast flood
ns-> set interface vlan1 broadcast arp
ns-> set interface vlan1 broadcast arp trace-route

As you execute CLI commands using the syntax descriptions in this manual, you may find
that certain commands and command features are unavailable for your NetScreen device
model.
Because NetScreen devices treat unavailable command features as improper syntax,
attempting to use such a feature usually generates the unknown keyword error
message. When this message appears, confirm the feature’s availability using the ?
switch. For example, the following commands list available options for the set vpn
command:

HW6FUHHQ3XEOLFDWLRQV

The Console port is an RJ-45 serial console port connector, for vt100 terminal emulator
programs to perform local configuration and administration.
The Modem port is an RJ-45 serial console port connector, for establishing remote console
sessions using dialup connections through a 9600 bps modem connected via an RS-232
cable. Dialing into the modem establishes the dialup console connection.
The table below lists the RJ-45 to DB-9 adapter connection definitions. To employ a
standard UART port, both the console and the modem ports use this configuration.

The NetScreen-204/-208 supports CompactFlash™cards with a variety of memory
capacities. NetScreen has tested SanDisk 96MB and 512MB cards. The NetScreen device
automatically detects the presence of a flash card and records the system log to it.
Warning! Because resetting the device restores it to the original factory default
configuration, any new configuration settings are lost, and the firewalland all VPN service
become inoperative.

A NetScreen-200 Series device can have an AC power supply or a DC power supply.
The DC power supply can operate on one or two DC feeds ranging from -36V to -60V.
When you use two feeds, they share the load. If one feed fails, the other automatically
assumes the full load.
The internal fuse for the DC power supply is a 3.15A/250V, fast-acting fuse. This is not
replaceable.
Note: Certain export restrictions may apply to international customers. Check with your
sales representative.

Each NetScreen-200 Series device uses a 2.5 amp, slow-blow power fuse rated for 250
volts.
To replace a fuse on a NetScreen-200 Series device:
1. Take the device off-line by turning the power switch OFF and disconnecting the
power cable.
2. Using a screwdriver, separate the lid of the external fuse cover from the surface
of the power outlet.
3. Gently remove the fuse assembly.
4. Slide the new fuse into the opening until the fuse clicks into place.
5. Replace the power cable and turn the device power switch ON.

Observing the following precautions can prevent injuries, equipment failures and
shutdowns.
•Never assume that the power supply is disconnected from a power source.
Always check first.
•Room temperature might not be sufficient to keep equipment at acceptable
temperatures without an additional circulation system. Ensure that the room in
which you operate the device has adequate air circulation.
•Do not work alone if potentially hazardous conditions exist.
•Look carefully for possible hazards in your work area, such as moist floors,
ungrounded power extension cables, frayed power cords, and missing safety
grounds.

The location of the chassis and the layout of your equipment rack or wiring room are
crucial for proper system operation.
Use the following guidelines while configuring your equipment rack.
•Enclosed racks must have adequate ventilation. An enclosed rack should have
louvered sides and a fan to provide cooling air.
•When mounting a chassis in an open rack, ensure that the rack frame does not
block the intake or exhaust ports. If you install the chassis on slides, check the
position of the chassis when it is seated all the way into the rack.
•In an enclosed rack with a ventilation fan in the top, equipment higher in the
rack can draw heat from the lower devices. Always provide adequate ventilation
for equipment at the bottom of the rack.
•Baffles can isolate exhaust air from intake air. The best placement of the baffles
depends on the airflow patterns in the rack.
You can mount the device in a standard 19-inch equipment rack. Rack mounting requires
the following tools:
•1 Phillips-head screwdriver
•Rack-compatible screws
•The supplied front-mount brackets
You can only front-mount a NetScreen-200 Series device.
Warning! To prevent abuse and intrusion by unauthorized personnel, it is extremely
important to install the NetScreen system in a locked-room environment.
