iTap GigaBit Dual Port Aggregator Chapter 1 Introduction Overview Thank you for purchasing the latest innovation in Tap technology – the iTap GigaBit Dual Port Aggregator. Net Optics' GigaBit Dual Port Aggregator Taps provide ultra-efficient access to critical 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.
iTap GigaBit Dual Port Aggregator cally when the traffic volume falls below the receiving capacity of the NIC. These buffers allow the iTap Port Aggregator to absorb traffic bursts without dropping packets. Traffic Monitoring The iTap Port Aggregator monitors the utilization levels of both sides of the fullduplex link. This information is displayed on the front panel and is available from the remote interfaces.
iTap GigaBit Dual Port Aggregator System Manager iTap Port Aggregators can be used as a system managed via Simple Network Management 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.
iTap GigaBit Dual Port Aggregator Memory All traffic that passes through the iTap is sent to the monitoring device NIC on a first-in-first-out basis, including traffic that is temporarily stored in memory. If two packets enter at the same time then one packet is processed while the other is stored briefly in memory, preventing collisions. When there is a burst of data, traffic in excess of the NIC’s capacity is sent to the iTap’s memory.
iTap GigaBit Dual Port Aggregator The NIC receives 800 Mbps (80% utilization), so no memory is required for the monitoring device's NIC to process all full-duplex traffic. If there is burst of traffic on Side A of 900 Mbps and Side B remains at 500 Mbps, the aggregated traffic equals 1400 Mbps, 400 Mbps over the capacity of the NIC. The excess traffic is put in memory on a first-in-first-out basis until either the buffer is full or the burst passes.
iTap GigaBit Dual Port Aggregator Unpacking and Inspection Carefully unpack the iTap GigaBit Dual Port Aggregator and check for damaged or missing parts.
