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.

Tip
You must have physical access to the Sensor when you configure a Sensor for the first time.

At any time during configuration, you can type a question mark (?) to get help on the Sensor CLI commands. Type commands for a list of all commands.

Log in to the Sensor using the terminal connected to the Console port.
At the prompt, log in using the default Sensor username (admin) and password (admin123).
(Optional, but recommended) Change the Sensor password. At the prompt, type passwd. The Sensor prompts you to enter the new password and asks you for the old password.
Note
A password must contain between 8 to 25 characters, is case-sensitive, and can consist of any alphanumeric character or symbol.
Set the Sensor mode to stack or standalone based on your requirement using the set sensor mode <stack | standalone> command.
You will be prompted to reboot the Sensor to change the mode. Press Y to confirm.
Set the name of the Sensor.
Tip
You can enter the setup command at the prompt which will automatically prompt you to provide the information shown in the subsequent steps of this section. Or, you can use the set command instead. If you use the set command, you must manually enter the complete command syntax as shown in the subsequent steps of this section.
- For a standalone Sensor, type: set sensor name <word> at the prompt.
  Example: set sensor name HR_sensor1
- For Sensors in the stack, type set stack name-node idat the prompt.
  Example: set sensor name NS9500_Stack-1
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.
You reset the Sensor to change the mode using the resetconfig command.
If the Sensor is not on the same network as the Manager, set the address of the default gateway. Type set sensor gateway <A.B.C.D> at the prompt.
Example:
set sensor gateway 192.168.3.68
Set the IP address of the Manager server. Type set manager ip <A.B.C.D> at the prompt.
Example:
set manager ip 192.168.2.8
Set the IP address and subnet mask of the Sensor. Type set sensor ip <A.B.C.D> <E.F.G.H> at the prompt.
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.
If prompted, reboot the Sensor. Type reboot
Note
The Sensor can take up to five minutes to complete its reboot.
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 the following command:
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 if the information is correct.
Set the shared secret key value for the Sensor. At the prompt, type the following command:
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 while adding the Sensor.
Type show to verify the configuration information. Check that all information is correct.
Type exit to exit the session.
