STEP 3: Configure the sensor
Configure sensor information
Configure the sensor with the network information, a name, and the
shared secret key that the sensor uses to establish secure
communication with the Manager. Use the name and key values you
set in Step 2.
Tip:
The first time you configure a sensor, you must have physical
access to the sensor.
At any time during configuration, you can type a question mark (
?
) to
get help on the sensor command-line interface (CLI) commands. For
a list of all commands, type
commands
.
1.
Log on to the sensor using the terminal connected to the Console
port.
2.
At the prompt, log on using the default sensor username (

3.
Optional, but recommended.
Change the sensor password:
At the prompt, type:
passwd
The sensor prompts you to enter the new password and prompts
you for the old password.
Note:
A password must contain between 8 and 25 characters, is
case-sensitive, and can consist of any alphanumeric character or
symbol.
4.
Set the name of the sensor:
Tip:
You can enter the setup command at the prompt and this will
automatically prompt you to provide the information shown in
items 4 through 7 and item 10. Or, you use the set command
instead. If you use the set command, you must manually enter the
complete command syntax as shown in items 4 through 7 and
item 10.
At the prompt, type:
set sensor name <WORD>
Example:
set sensor name HR_sensor1
Note:
The sensor name is a case-sensitive character string up to
25 characters. The string can include hyphens, underscores, and
periods, and must begin with a letter.
5.
If the sensor is not on the same network as the Manager, set the
address of the default gateway:
At the prompt, type:
set sensor gateway <A.B.C.D>
Example:
set sensor gateway 192.168.3.68
6.
Set the IP address of the Manager server:
At the prompt, type:
set manager ip <A.B.C.D>
Example:
set manager ip 192.168.2.8
7.
Set the IP address and subnet mask of the sensor:
At the prompt, type:
set sensor ip <A.B.C.D> <E.F.G.H>
Example:
set sensor ip 192.168.2.12 255.255.255.0
Note:
Specify an IP address using four octets separated by
periods: X.X.X.X, where X is a number between 0 and 255,
followed by a subnet mask in the same format.
8.
If prompted, reboot the sensor:
Type:
reboot
Note:
The sensor can take up to five minutes to complete its
reboot.
9.
Ping the Manager from the sensor to determine if your
configuration settings to this point have successfully established
the sensor on the network:
At the prompt, type:
ping <manager IP address>
If the ping is successful, continue with the following steps. If not,
type
show
to verify your configuration settings and check that the
information is correct.
10.
Set the shared secret key value for the sensor:
At the prompt, type:
set sensor sharedsecretkey
.
The sensor then prompts you to enter and, subsequently, confirm
the shared secret key value.
Note:
This value is used to establish a trust relationship between
the sensor and the Manager. The secret key value can be
between 8 and 25 characters of any ASCII text. The shared key
value is case-sensitive. Make sure the value matches the shared
secret key value you provided in the Manager interface.
11.
To verify the configuration information, type

. Check that all
information is correct.
