These buffers allow the iTap Port Aggregator to absorb traffi c bursts without dropping packets. Traffi c Monitoring The iTap Port Aggregator monitors the utilization levels of both sides of the full- duplex link. This information is displayed on the front panel and is available from the remote interfaces. The iTap Port Aggregator allows you to set a threshold for each side of the ful

iTap GigaBit Dual Port Aggregator System Manager iTap 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. As with Web Manager, you can view all status, confi guration, and traffi c information and make ch

iTap GigaBit Dual Port Aggregator 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 y in memory, preventing collisions. When there is a burst of data, traffi c in excess of the NIC’s capacity is sent to the iTap’s memory. Memory continues to fi ll until its capacity is reache

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 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 c equals 1400 Mbps, 400 Mbps over the capacity of the NIC. The excess traffi c is put in memory on a fi rst-in-fi rst-out basis until either the buf- fer is full or the burst passes. Side A iTap GigaBit Dual Port Aggregat
