iLink Agg  Xstream™ Logo The need to monitor expanding volumes of 10 Gbps traffic is straining CAPEX budgets due to the high cost of 10G monitoring tools. The iLink Agg Xstream helps you leverage your monitoring tool investments by:
  • Enabling existing 1G tools to be applied to 10G traffic
  • Providing the ability to take advantage of the full bandwidth of 10G tools
  • Supplying more port density than any other 1U form factor link aggregator
iLink Agg xStream - Link Aggregator
The iLink Agg Xstream is a link aggregator that combines traffic from as many as 20 network links or Span ports and sends it to four monitoring tools. Each of its 24 SFP+ ports accepts both 10G SFP+ and 1G-SFP transceivers, enabling 10G and 1G links, Span ports, and monitoring appliances to interconnect in any mix of speeds, including different fiber and copper media types.

Key Features

Passive, Secure Technology
  • Increases monitoring efficiency by enabling tools to view the traffic on as many as 20 network links (from external Taps or Port Aggregators) or 20 Span ports simultaneously
  • Improves monitoring flexibility with fully configurable port mappings (any number of links to any number of tools)
  • Provides complete visibility at 10 Gbps without interfering with the data stream and without introducing a point of failure
  • Supports media type and data rate conversion with SFP+ or SFP transceiver modules on both the network and monitor ports
  • Enhances monitoring security because no IP address is needed
  • Provides RMON statistics such as packet counts, bandwidth utilization, and threshold alarms to increase monitoring efficiency
  • No interference with the data stream and no point of failure introduced
  • Remote traffic statistics and configuration
  • Security options control user access
  • Redundant power ensures uptime
  • Compatible with all Net Optics Taps
  • IEEE 802.3 compliant
  • Fully RoHS compliant
  • All Net Optics products come standard with a 1 year manufacturer's warranty
  • Optional 1 or 2 year extended warranty available at time of product purchase
Ease of Use
  • Pre-loaded with common port mapping configurations
  • LEDs indicate Link, Activity, and Power status
  • Net Optics Indigo management software enables remote configuration and monitoring of multiple iLink Agg Xstream and other iTap-enabled devices throughout the network
  • Front-mounted connectors ease installation and operation
  • Compatible with all major manufacturers' monitoring devices, including protocol analyzers, probes, firewalls, and intrusion detection and prevention systems
The iLink Agg Xstream automatically performs all data-rate and media-type conversions, enabling 10G traffic to be sent to 1G appliances, and 1G traffic to 10G tools. This capability protects your security appliance investment, because the iLink Agg Xstream enables you to apply your existing arsenal of 1G monitoring tools to your new 10G traffic links. You can aggregate the traffic from multiple 1G links and low-utilization 10G links to fill up the bandwidth of expensive 10G tools.

Flexible Port Mapping

The iLink Agg Xstream device supports fully configurable port mapping, so it can provide many other configurations in addition to 20 network ports to four monitor ports. Preloaded aggregation configurations include:
  • A single 20x4 link Aggregator
  • Dual 10x2 aggregators
  • Quad 4x2 aggregators
Preloaded regeneration configurations include:
  • 1-to-23
  • Dual 1-to-11
  • Quad 1-to-5
In addition, any port can function as a network port or a monitor port, so you can attach more than four monitoring tools or more than 20 network links, if required. Splitting the cables into separate transmit and receive fibers makes a total of 24 network inputs and 24 monitor outputs available for concurrent use. The network inputs can be connected to external Taps or switch Span ports. Direct in-line link connections are not supported.

Information Intelligence

iTap functionality provides RMON traffic statistics so you can view link utilization levels and error rates in real time. A 10/100/1000 management port enables remote management and monitoring from anywhere in the network, giving you the information you need to quickly respond to network events.

Dual Power Supplies

The iLink Agg Xstream has two independent power supplies that provide fault tolerance: If one power supply loses power, the unit continues operating on the remaining supply. The power supply modules are hot-swappable, so your monitoring capability does not need to be interrupted if a power supply needs replacement. Both universal AC and -48VDC (telco) models are available.

Easy Configuration

Indigo™ management software provides a command-line interface (CLI) for setting iLink Agg Xstream parameters and checking status and traffic statistics with a few keystrokes. The CLI can be accessed locally through an RS232 serial port, or remotely with a secure SSH connection. GUI management interfaces will be available in the near future.


Security and Reliability

The iLink Agg Xstream is a secure and reliable appliance that delivers unsurpassed monitoring access flexibility. It handles network traffic entirely in hardware, so there is no software to be loaded, maintained, or compromised. (The secure embedded management firmware cannot disrupt the network data path.) Configuration variables and TapFlow filters can be changed only through the device's management port, so your monitoring access is immune to viruses, worms, and other attacks that pass through the iLink Agg Xstream network ports. The iLink Agg Xstream maintains its configuration when power is absent, making it a true appliance.

Zero Dropped Packets

The iLink Agg Xstream scans incoming traffic from the network ports on a first-in-first-out basis. The scan rate is optimized to ensure that no packets are dropped as long as the sum of data rates on the network ports does not exceed the monitoring port capacity of 10 Gbps (or 1 Gbps for monitor ports with 1G SFP transceivers).
