AWN101 Sensor Mirroring Deployment
Deploy an AWN101 Sensor with port mirroring Direct link to this section
The AWN101 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 Direct link to this section
Verify that you received the following items from Arctic Wolf:
Note: Your sensor has a tamper-evident asset ID: AWN-12XXXXXX. Contact email@example.com if the asset ID is missing or was tampered with.
Three CAT6 RJ45 Ethernet cables, 2m
Crossover RJ45 Ethernet cable (red), 2m — Use only if needed
Mini USB to USB 2.0 adapter cable, 0.5m
AC30 US power cord, 2m
Set of rack ears — Use only if needed
For best performance, do not rate-limit the sensor with Quality of Service (QoS).
If your firewall does SSL/TLS inspection, AllowList the sensor management IP address, and then check that your firewall allows outbound access from that IP address over port 443 to the necessary IP addresses.
To see the complete list of IP addresses that you must allowlist, go to the Arctic Wolf Portal, and then click Account > Arctic Wolf IP Addresses. The IP addresses that must be allowlisted are listed under If you are a Managed Detection and Response (MDR) customer.
Steps Direct link to this section
- Set up a customer-configured appliance.
- Install the hardware.
- Connect the sensor for mirroring deployment.
Step 1: Set up a customer-configured appliance Direct link to this section
Note: This step only applies if you selected customer-configured appliance on your onboarding form.
See Set up a customer-configured appliance for additional information.
Step 2: Install the hardware Direct link to this section
Install the sensor in the applicable rack location.
If necessary, use the provided rack ears.
Using a CAT6 RJ45 Ethernet cable, connect the management port (port 4) on the sensor to the outbound connection on your network switch.
Connect the AC30 US power cord to the power supply.
Thread one end of the power supply to the AC-adapter connector on the sensor, and then plug the other end into a power source.
Turn on the sensor power.
The Power LED is green when the sensor power is on.
Ping the management IP address that you provided to Arctic Wolf to check network connectivity.
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.
If you cannot successfully complete these steps, email firstname.lastname@example.org.
Step 3: Connect the sensor for mirroring deployment Direct link to this section
Configure up to three 1G ports on your network switch as mirror ports.
See the setup instructions provided by your network switch manufacturer for more information:
Create a 1G mirror connection. Using a CAT6 RJ45 Ethernet cable, connect port 1 (LAN0) on the sensor to a mirror port on your network switch.
(Optional) Create an additional 1G mirror connection. Repeat the previous step with one of the following ports:
- Port 2 (LAN1)
- Port 3 (LAN2)
If you are configuring optional layer 3 mirroring, email email@example.com with the following 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.
See Configure optional layer 3 mirroring for more information.
Email firstname.lastname@example.org to confirm that Arctic Wolf is seeing your network traffic.
Configure optional layer 3 mirroring Direct link to this section
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 Concierge Security Team® (CST) or email@example.com to configure this option.
