Director

Chapter 1

Introduction

Net Optics Director is a key component for building a comprehensive, consolidated monitoring infrastructure for both

network management and security. It extends the range of visibility for data monitoring across converged data and

digital voice networks, while eliminating monitoring port contention and minimizing the number of tools needed to

optimally manage the network.

A single Director device enables you to tap into multiple network links, and direct their trafc to multiple monitoring

ports. It includes aggregation and regeneration functions, so the link-to-monitor-port mapping can be one-to-one,

one-to-many, many-to-one, or many-to-many. In addition, it provides ltering: Each Monitor port can be programmed

to receive only trafc meeting user-dened lter criteria based on protocol, source and destination addresses, and

network utilization. This ltering capability enables specic types of trafc such as voice over IP (VoIP) to be directed

to particular monitoring tools.

Matrix switching, aggregation, and regeneration

Each Director chassis supports up to 12 in-line network links or 26 Span ports. For monitoring, up to 12 ports are

provided. Network and Span ports can be aggregated and regenerated to output ports in almost any combination.

Modular design

Director is modular to provide conguration exibility.

Director Network Modules (DNMs) support SX (multi-mode) and LX (single-mode) ber links and 10/100/1000 •

Copper links.

Each DNM provides either 6 in-line network links or 12 Span ports.•

The Director Chassis includes two DNM slots; they can be populated with the same or different DNM types.•

Ten 1-Gigabit Monitor ports are SFP-based, accepting any mix of Copper, SX, and LX interface modules. •

Four 10-Gigabit ports are XFP-based, accepting SR, LR, and ER interface modules. •

Flexible 10 Gigabit support

Two 10 Gigabit ports on the front of the unit can be congured as Network, Span, or Monitor ports. They can be

congured for the same or different functions. Trafc from multiple 1-Gigabit Network or Span ports can be aggregated

to a 10-Gigabit Monitor port. Conversely, trafc from a 10 Gigabit Network or Span port can be dis-aggregated to

multiple 1 Gigabit Monitor ports through appropriate ltering. For example, trafc from different IP address ranges

could be directed to separate Monitor ports.

Expandable

An additional two 10 Gigabit ports on the rear of the unit enable daisy-chaining up to ten Director chassis to expand the

number of available ports, for a total of 380 ports in a fully expanded system (when available).

Monitor port-based ltering

Director avoids the confusion of pre-ltering versus post-ltering by strictly tying ltering to the Monitor ports. Each

Monitor port can be congured to have trafc from any number of Network or Span ports directed to it, and each Monitor

port applies up to 30 protocol-, address-, and utilization-based lters to the trafc.
