AWN202 Sensor - Mirroring Deployment

Updated Nov 13, 2023

Deploy an AWN202 Sensor with port mirroring

You can deploy an AWN202 Sensor with port mirroring.

The AWN202 Sensor is an external network device that allows you to monitor network traffic. When the sensor is deployed with port mirroring, a switch sends a copy of all network packets that are seen on one port to another port.

This image provides a simplified network map of a sensor with mirroring deployment:

Before you begin

Steps

  1. Set up a customer-configured appliance.
  2. Install the hardware.
  3. Connect the sensor for mirroring deployment.

Step 1: Set up a customer-configured appliance

Note: This step only applies if you selected customer-configured appliance on your onboarding form.

See Set up a customer-configured appliance for more information.

Step 2: Install the hardware

  1. Install the sensor in the applicable rack location.

    If needed, use the provided rack ears.

  2. Using a CAT6 RJ45 Ethernet cable, connect the management port (port 1) on the sensor to the outbound connection on your network switch.

  3. Using the AC30 US power cord, connect the power connector on the sensor to a power source.

  4. Turn on the sensor power.

    The power LED is green when the sensor power is on.

  5. Ping the management IP address that you provided to Arctic Wolf to check network connectivity.

  6. Wait 15 minutes, and then make sure the status LED is green. This shows that the sensor is connected to the Arctic Wolf monitoring service.

  7. If you cannot successfully complete these steps, contact your CST at security@arcticwolf.com.

Step 3: Connect the sensor for mirroring deployment

  1. Configure up to five 1G ports as mirror ports on your switch.

    See the configuration instructions provided by your network switch manufacturer for more information:

  2. Create a 1G mirror connection. Using a CAT6 RJ45 Ethernet cable, connect port 2 (LAN24) on the sensor to a mirror port on your network switch.

  3. (Optional) Create additional 1G mirror port connections. Using a CAT6 RJ45 Ethernet cable, connect any of these ports on the sensor to a mirror port on your network switch:

    • Port 6 (LAN0)
    • Port 5 (LAN1)
    • Port 4 (LAN2)
    • Port 3 (LAN3)

    Note: When connecting multiple RJ45 mirroring interfaces from the same switch to a sensor, make sure that the mirroring interfaces do not connect to the same bridge pair.

    The bridge pairs for this sensor are: port 5 and port 6 or port 3 and port 4.

  4. If you are configuring optional layer 3 mirroring, contact your CST at security@arcticwolf.com. Include this information:

    • LAN<ID>, IP address, and netmask of the optional LAN interface.
    • TCP/IP port, if the default port (4789) is not used for a VXLAN environment.
    • Confirmation that the management IP address and LAN<ID> IP address are not on the same subnet.
  5. Contact your CST at security@arcticwolf.com to confirm that Arctic Wolf is seeing your network traffic.

Configure optional layer 3 mirroring

You can configure optional layer 3 mirroring on the sensor to receive network traffic from a remote IP address to the AWN Sensor through LAN 1. This configuration allows a sensor to be deployed anywhere that supports Encapsulated Remote Switched Port Analyzer (ERSPAN).

Note: For physical sensors, the management port IP address and lan<ID> IP address cannot be on the same subnet.

This optional configuration requires assigning a static IP address to lan<ID> for a physical sensor or lan0 for a virtual sensor. The sensor does not support DHCP or DHCP reservation for the LAN IP address. Contact your CST at security@arcticwolf.com to configure this option.
