NSE-X2 connections and environmental specifications
Introduction
All Network Service Element come in two varieties: SPAN and TAP.
The SPAN model has two independent monitor interfaces. In a typical configuration, both ports will be connected to two SPAN output ports: one port duplicating all packets from the network to the site and the other port duplicating all packets in the opposite direction. This application offers great WAN visibility, including more precise traffic measurements than possible with flow based analysis or snmp. Other applications are possible, such as the monitoring of server traffic in a relatively small remote datacenter.
The fail-safe TAP model has been designed to be installed inline between the WAN Access Device and the local switch. No specific configuration of those devices is required.
Solution
Physical location
Make sure the ventilation holes on the left and right side of the appliace do not become obstructed so air can flow freely trough the appliance.
NSE are fan-less. Make sure the appliance is not positionned in the exaust of any other device.
Network connections (appliance rear view)
 | NSE does not provide nor pass PoE to a Powered Device (PD). Use a power adapter or inline PoE injector to power the PD. |
The picture above shows a MINIMAL SET of ports that must be connected. Connection to additional ports may be required in specific situations.
LAN1 & LAN2: out-of-band MANagement. Connect at least one of these ports to a local switchport.
SPAN model with out-of-band management:
LAN1 & LAN2: out-of-band MANagement. Connect at least one of these ports to a local switchport.
LAN3 & LAN4 are both MONitor ports. Connect at least one port to a packet broker or to the egress port of a monitor/mirror session (*). By default, both ports are aggregated into one Monitored Element.
Fail-safe TAP model with optional inline management:
LAN1 & LAN2: These ports are disabled.
To monitor the entire site, install the appliance between the WAN Access Device and the local switch:
Connect LAN3 to the WAN Access Device (i.e., facing the network).
Connect LAN4 to the LAN Access Device (i.e., facing the site)
