GigaBit links using only one NIC on the monitoring device. Net Optics’ iTap is a port aggregator Tap that gives you a quick visual reference of link performance. The iTap GigaBit Port Aggregator monitors and displays link bandwidth utilization on its front panel so you can see exactly what is happening on both sides of the network link.
Web Manager Net Optics' Web Manager is the browser-based interface that allows you to change settings, view status, and retrieve data remotely with simple-to-use controls. When you access an iTap Port Aggregator with Web Manager, all confi gurations, status, and traffi...

Port Aggregators can be used as a system managed via Simple Network Man- agement Protocol (SNMP) from a single interface. Net Optics' System Manager is an SNMP management tool that offers central management of all Net Optics iTap devices in the network. You can organize iTaps into groups according to workgroup, location, or any other criteria.
Memory All traffi c that passes through the iTap is sent to the monitoring device NIC on a fi rst-in-fi rst-out basis, including traffi c that is temporarily stored in memory. If two packets enter at the same time then one packet is processed while the other is stored briefl...

The NIC receives 800 Mbps (80% utilization), so no memory is required for the monitoring device's NIC to process all full-duplex traffi c. If there is burst of traffi c on Side A of 900 Mbps and Side B remains at 500 Mbps, the aggregated traffi...
You may have also ordered a one rack unit panel for rack mounting the iTap GigaBit Port Aggregator and an extended warranty. Carefully check the packing slip against parts received. If any part is missing or damaged, contact Net Optics' Customer Service immedi- ately. About this Guide This Guide provides you all the information you need to confi...

® www.netoptics.com Figure 13: 96547iTP Monitor Connections Connecting Power For power fault protection, the iTap has redundant power supplies. The second power supply is available to support the fl ow of traffi c to the monitoring device in the event that the fi rst power supply becomes unavailable. If the fi rst power supply is unavailable, the second power supply provides all power for the iTap.
Verify that the Management Port is functional by typing the iTap's IP address in your Web browser. Net Optics' Web Manager should appear. If it does not, check the Management Port cables and connections and verify that the Display option in the CLI is set to ON.
Using the Front Panel Interface Overview This chapter describes how to interpret and work with the front panel features of the iTap GigaBit Dual Port Aggregator. The following topics are covered: • Display • LED indicators • Reset Button The iTap front panel provides information in two ways. The displays shows utiliza- tion and peak information and the LEDs show link status and alarm conditions.
The percentage utilization data on the display is refreshed every second. Network peaks are given as a percent of utilization and refl ect the highest peak recorded since the last reset. The day and time information refl ects the highest peak event since reset.
Overview This chapter describes how to monitor and control individual iTap GigaBit Port Aggregators using Web Manager. The following topics are covered: • Accessing Web Manager • Status • Statistics • Confi guration The iTap GigaBit Port Aggregator has built-in support for remote control from any computer with an Internet browser and access to the iTap’s IP address.
