NSE-X2 connections and environmental specifications
Introduction
All Network Service Elements come in two varieties: SPAN and TAP.
The SPAN model has two independent monitor interfaces. In a typical configuration, both ports are 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 oposite ditection. This offers great WAN visibility, and more precise measurements that possible with flow based analysis or snmp. Other applications of the same model are possible, for example the monitoring of packets in a 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.

Network connections (appliance rear view)
This picture shows the minimal set of ports that must be connected in order to operate normally. More connections ma required
All models:
LAN 1: MANagement port: this port must be connected to a local switchport.
SPAN model:
LAN 3: MONitor port: this port must be connected to the SPAN representing the traffic FROM the network*.
LAN 4: MONitor port: this port must be connected to the SPAN representing the traffic TO the network*.
TAP model (inline):
Install the appliance between the WAN Access Device and the local switch. Connect LAN3 to the WAN access device and LAN4 to the local switch. The applicance does not provide PoE.
