The following information applies to ExtraHop Discover, Command, Explore, and Trace hardware appliances.
Lights-out management (LOM), which enables remote management of the appliance.
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.
For the EDA 1100, 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.
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 Web UI and Admin UI or to the ExtraHop REST API.
The Discover and Command have both a Web UI and an Admin UI. The Explore and Trace appliances have an Admin UI only. All appliances have a REST API.
Depending on the appliance, RJ45 Ethernet or fiber (SFP+ LC).
On the Discover, 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)
While 10 GbE management + capture interfaces on the EDA 10200, EDA 9200, and ETA 8250 can conduct management functions at 10 Gbps speeds, processing traffic such as ERSPAN is limited to 1 Gbps.
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.
Connect these interfaces to your traffic sources:
- The links where your ERSPAN or RPCAP software taps are installed
- The links where your SPAN sessions are configured
- A SPAN or software tap aggregation switch
Management interfaces that are not the primary interface are disabled by default.
Interfaces 5-6 are available on the 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.
The 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.
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.
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
