Introduction

Passive Fiber Optic TAPs require little or no configuration. While cabling the network - and site ports is straight forward, the cabling between the TAP output and the NETSCOUT Accelerator NIC is somewhat special.

 

Solution

 

 

LC SM/MM HD Fiber TAP

TAP internal cabling

Cables required

The two fibers of the duplex LC-LC output of the TAP - indicated with "monitor" - are both used for transmission.

To connect to the NETSCOUT Accelerator NIC, you need a LC-LC-duplex to 2x LC-simplex fan-out cable. It is very easy to make a cable like that.

Connecting the TAP to the NETSCOUT accelerator NIC

Both LC-simplex connectors need to be connected to the input of two separate SFP/SFP+ ports on the NETSCOUT Accelerator NIC on the back of the appliance.

Link aggregation

To analyze the date from the TAP correctly, you MUST create an aggregate that includes the two ports on the accelerator NIC connected to the TAP. In this example, those interfaces are if3 and if4. Read the Agent Configuration Utility for CDM/ASI Administration Guide for details on how to do this.
