Deploy the EDA 10300 sensor

This guide explains how to install the rack-mounted EDA 10300 sensor.

This installation enables you to run network performance monitoring, network detection and response, and intrusion detection on a single sensor. By adding the IDS module, you can also upload and view IDS detections.

Important:The IDS module requires the NDR module. Before you can enable the IDS module on this sensor, you must upgrade the sensor firmware to version 9.6 or later. When the upgrade completes, you can apply the new license to the sensor.
Note:If you have enabled the IDS module on this sensor, and your ExtraHop system does not have direct access to the Internet and access to ExtraHop Cloud Services, you will need to upload IDS rules manually. For more information, see Upload IDS rules to the ExtraHop system through the REST API.

Installation prerequisites

To install the sensor, your environment must meet the following requirements:
Sensor
2U of rack space and electrical connections for 2 x 800 W power supplies.
Management
One 10/100/1000BASE-T network port or one 10GBASE-SR port for sensor management.
Monitoring (capture)
High performance interfaces: One to six network ports for connection to 100 GbE, 40 GbE, 25 GbE, or 10 GbE sources of packet data.
Management + monitoring interfaces: One to two network ports for connection to 1 GbE sources of packet data.
Network Access
Ensure that administrators can access the Administration settings on the sensor over TCP port 443.
Configure your firewall rules to allow outbound access over port 443 to ExtraHop Cloud Services.

For more information about the interfaces on the ExtraHop system, see the ExtraHop Hardware FAQ.

Rear panel ports

EDA 10300

  1. Four 100 GbE-capable ports on two network adapters. These ports are high-performance monitoring (capture) interfaces.
  2. One RS-232 serial port to connect a console device
  3. Power supply unit (PSU2) to connect the sensor to an AC power source
  4. One VGA port to connect an external display
  5. Two USB 3.0 ports to connect input devices such as a keyboard and mouse
  6. One iDRAC interface port
  7. Two 10 GbE ports. These ports can be configured as a management port or management and RPCAP/ERSPAN/VXLAN/GENEVE target. These ports also function as high-performance monitoring (capture) interfaces.
    Note:Processing RPCAP, ERSPAN, VXLAN, and GENEVE traffic is limited to 1 Gbps per interface in "Management + RPCAP/ERSPAN/VXLAN/GENEVE" modes, but the ports support up to 10 Gbps per interface in Monitoring and High-Performance ERSPAN/VXLAN/GENEVE target modes.
  8. Two 10/100/1000BASE-T network ports. Port 1 is the primary management port. These ports can be configured as a monitoring port, management port, or management and RPCAP/ERSPAN/VXLAN/GENEVE target.
  9. Power supply unit (PSU1) to connect the sensor to an AC power source

Note:The packet processing capability of the sensor is 100 Gbps. While it is possible to oversubscribe the sensor by sending more than 100 Gbps of packet data across the four 100 GbE-capable ports, inbound workloads that exceed 100 Gbps will result in dropped packets.

Traffic distribution guidelines

  • Packets from the same flow should be received on the same interface, or on interfaces of the same network interface card (NIC).
  • The ingest on each NIC should not exceed 75% of the rated analysis throughput for the sensor to ensure that traffic is balanced across system resources.
  • If your data feed does not require both interfaces on the NIC, disable the unconfigured interfaces in the Administration settings. For example, configure the sensor with a single interface to ingest 50 Gbps on each NIC. Disable the extraneous ports on each NIC. This configuration optimizes performance for 100 Gbps.
  • A single high-performance ERSPAN target is expected to process 20 to 30 Gbps. On larger sensors, distribute ERSPAN traffic to more interfaces to scale traffic ingest.

Set up the sensor

  1. Rack mount the sensor.
    Install the sensor in your data center with the included rack-mounting kit. The mounting kit supports most four-post racks with either round or square holes.

    Orient the hardware to ensure proper airflow. The cold air intake is through the front of the sensor.

  2. Connect port 1 to your management network.
    This sensor has two 10/100/1000BASE-T network ports. With a network patch cable, connect the management port on the sensor to your management network. Port 1 is the primary management port.
  3. Connect the monitoring port.
    With the appropriate network cable, connect a monitoring port on the sensor to a network tap or mirror port on the switch. When configuring multiple high-performance monitoring ports, you can consider balancing the transceivers across adapters. For example, with two transceivers, connect the cable to the transceivers on port 5 and port 7.
    Important:To ensure the best performance for initial device synchronization, connect all sensors to the console and then configure network traffic forwarding to the sensors.
    Note:The link lights on the monitoring interface ports do not illuminate until you register the ExtraHop sensor, recordstore, or packetstore with your product key.
  4. (Optional): Connect the iDRAC port.
    To enable remote management of the sensor, connect your management network to the iDRAC port with a network patch cable.
  5. Install the front bezel.
    You must install the front bezel if you want to configure the sensor through the LCD display.

    Insert the USB connector on the right side of the bezel into the USB port on the front of the sensor. Press and hold the release button on the left end of the bezel and push the bezel flush with the sensor until it snaps into place.

  6. Connect the power cords.
    Connect the two supplied power cords to the power supply units (PSUs) on the back of the sensor, and then plug the cords into a power outlet. If the sensor does not power on automatically, press the power button on the front-right of the sensor.

Management IP address configuration

DHCP is enabled by default on the ExtraHop system. When you power on the system, the primary management interface attempts to acquire an IP address through DHCP. If successful, the IP address appears on the home screen of the LCD.

If your network does not support DHCP, you can configure a static IP address through the LCD menu on the front panel or through the command-line interface (CLI).

Important:We strongly recommend configuring a unique hostname. If the system IP address changes, the ExtraHop console can re-establish connection easily to the system by hostname.
