3. On the Network Settings for Interface
<interface number>
page, select one of the following options
from the
Interface Mode
drop-down:
Option
Description
Disabled
The interface is disabled.
Monitoring Port (receive only)
Monitors network traffic.
Management Port
Manages the ExtraHop appliance.
Management Port + Flow Target
Manages the ExtraHop appliance and captures
traffic forwarded from a flow network.
Note:
If you enable NetFlow on the EDA 1100
or EDA 1000v, you must disable Interface
2. These appliances cannot process
NetFlow and wire data simultaneously.
Management Port + RPCAP/ERSPAN/VXLAN
Target
Manages the ExtraHop appliance and captures
traffic forwarded from a packet forwarder,
ERSPAN*, or VXLAN**.
While 10 GbE mana 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.
Tip:
In environments with asymmetric
routing adjacent to the high-
performance interfaces, ping replies
might not get back to the sender.
High-Performance ERSPAN/VXLAN Target
Captures traffic forwarded from ERSPAN* or
VXLAN**. This interface mode enables the port to
handle more than 1 Gbps. Set this interface mode
if the ExtraHop appliance has a 10 GbE port. This
interface mode only requires that you configure
an IPv4 address.
*The ExtraHop system supports the following ERSPAN implementations:
•
ERSPAN Type I
•
ERSPAN Type II
•
ERSPAN Type III
•
Transparent Ethernet Bridging. ERSPAN-like encapsulation commonly found in virtual switch
implementations such as the VMware VDS and Open vSwitch.
**Virtual Extensible LAN (VXLAN) packets are received on UDP port 4789.
Note:
For Amazon Web Services (AWS) deployments with one interface, you must select
Management Port + RPCAP/ERSPAN/VXLAN Target
for Interface 1. If you are
configuring two interfaces, you must select
Management Port + RPCAP/ERSPAN/
VXLAN Target
for Interface 1 and
Management Port + RPCAP/ERSPAN/VXLAN Target
for Interface 2.
4. (Optional) Select an interface speed.
Auto-negotiate
is selected by default, however, you should
manually select a speed if it is supported on your appliance, network transceiver, and network switch.
