Appliance Hardware FAQ
The following information applies to ExtraHop Discover, Command, Explore, and Trace hardware appliances.
- What kind of connection does the iDRAC interface require?
- What is the iDRAC interface for?
- Does this interface require an IP address?
- Should that IP address be on the same subnet as the Discover appliance management and capture interfaces?
- What switch do I connect the iDRAC interface to?
- Can I update the iDRAC controller firmware?
Primary Management Interface
Additional Capture Interfaces
What is the iDRAC interface for?
Lights-out management (LOM), which enables remote management of the ExtraHop system.
Should that IP address be on the same subnet as the Discover appliance management and capture interfaces?
The iDRAC IP address can be on the same subnet as the management interface.
What switch do I connect the iDRAC interface to?
Connect iDRAC to your management network and VLANs and make sure that your ExtraHop administrators can access the iDRAC IP address.
Can I update the iDRAC controller firmware?
Yes. The iDRAC controller firmware is not updated with the firmware for the ExtraHop system. If you want to take advantage of iDRAC firmware enhancements, follow the instructions on the Dell Technologies website to upgrade the firmware.
Primary Management Interface (1 or 3)
Which port is the primary management interface?
For the EDA 1100, EDA 4200, EDA 6100, EDA 6200, EDA 8100, EDA 8200, and EDA 9100, interface 1 is the primary management port.
For the EXA 5200, ETA 6150, ETA 8250, EDA 9200, and EDA 10200, interface 3 is the primary management port.
What is this interface for?
The primary management interface is the interface that will attempt to acquire an IP address over DHCP when the appliance first boots after arrival from the factory.
This interface provides both management access to the appliance and can be configured for management plus NetFlow or management plus RPCAP, ERSPAN, and VXLAN. Access is available through a web browser to the ExtraHop system or to the ExtraHop REST API.
Additional Capture Interfaces (1-4)
What kind of connection do these interfaces require?
Depending on the appliance, RJ45 Ethernet or fiber (SFP+ LC).
What are these interfaces for?
On the Discover appliance, these interfaces can be configured as follows:
- As additional dedicated management interfaces
- As management interfaces with auxiliary capture capabilities for the following IP-based
- NetFlow (Discover appliances only)
- As capture interfaces for raw packet feeds such as SPAN (1 GbE interfaces only)
|Tip:||In environments with asymmetric routing adjacent to the high-performance interfaces, ping replies might not get back to the sender.|
Do these interfaces require an IP address?
Yes, if configured as a management port or if processing NetFlow, ERSPAN, RPCAP, or VXLAN target.
Can the primary management IP address be on the same subnet as these management + capture interfaces?
No. All management-capable interfaces having an IP address must be configured with distinct subnets.
What switch do I connect these interfaces to?
Connect these interfaces to your traffic sources:
- The links where your ERSPAN or RPCAP forwarders are installed
- The links where your SPAN sessions are configured
- A SPAN or packet forwarder aggregation switch
Management interfaces that are not the primary interface are disabled by default.
Primary Capture Interfaces (Interfaces 5-8)
Which interfaces are available on ExtraHop appliances?
Interfaces 5-6 are available on the EDA 4200, EDA 6100, EDA 6200, EDA 8100, EDA 8200, ETA 6150, and ETA 8250.
Interfaces 5-8 are available on the EDA 9100, EDA 9200, and EDA 10200.
What kind of connection do these interfaces require?
The EDA 4200, EDA 6100, EDA 6200, EDA 8100, EDA 9100, and ETA 6150, interfaces are equipped with 10GBASE-SR transceivers. These appliances connect to your equipment through fiber cables to 10GBASE-SR transceivers or through customer-supplied SFP+ DAC (twinax) cables.
The EDA 8200, EDA 9200 and ETA 8250 interfaces are equipped with 25GBASE-SR transceivers. These appliances connect to your equipment through fiber cables to 25GBASE-SR or 10GBASE-SR transceivers or through SFP28 DAC cables that you supply.
The EDA 10200 interfaces are equipped with 100GBASE-SR4 transceivers in their factory default configuration. These appliances connect to your equipment through fiber cables and 40GBASE-SR4 or 100GBASE-SR4 transceivers or through QSFP28 DAC cables that you supply, The EDA 10200 can be ordered with 25GBASE-SR transceivers for connection to your equipment similar to the ETA 8250.
What kind of fiber optic cable is required?
Appliances with 10GBASE-SR and 25GBASE-SR transceivers require 850nm multi-mode fiber cables with LC connectors.
The 10200 with 100GBASE-SR4 transceivers require 850nm multi-mode fiber cables with MPO connectors.
Who provides the transceivers?
On all appliances except for the EDA 10200, ExtraHop provides one SFP transceiver for each appliance interface.
The EDA 10200 has a total of four ports. The factory default appliance configuration has two ports with 100GBASE-SR4 transceivers and two open ports. You can order two or four 25GBASE-SR transceivers for the four available ports.
You must provide an SFP transceiver that is compatible with your switch
