iTap 10 GigaBit Port Aggregator Chapter 1 Introduction Thank you for purchasing the latest innovation in Tap technology, the iTap 10 GigaBit Port Aggregator (iTap Port Aggregator). This device provides ultra‑efficient access to critical 10 Gigabit full-duplex links using only one NIC on each monitoring tool, and supports two tools simultaneously.
iTap 10 GigaBit Port Aggregator Performance Aggregation The iTap Port Aggregator combines and regenerates both directions of a full‑duplex stream, sending all aggregated traffic to two separate monitoring ports. Typically, full-duplex monitoring with a network tap requires two network interface cards (NICs) (or a dual channel NIC), one interface for each side of the full-duplex link.
iTap 10 GigaBit Port Aggregator User-defined Maximum Packet Size The user can set a maximum packet size of 64 to 12,000 bytes for each network port. If any oversized packets are received (the packet length exceeds the programmed value), they are counted and discarded. This function enables the iTap Port Aggregator to pass jumbo packets, but discard packets that are oversized as defined by the user.
iTap 10 GigaBit Port Aggregator CRC Sanitizing The iTap Port Aggregator can be set to drop packets from the monitoring data stream if they are received with CRC errors. This function can clean up the data being sent to monitoring tools, or it can be left off so the monitoring tool can see the packets that have CRC errors. In either case, packets received with CRC errors are counted and reported in the Port Statistics.
iTap 10 GigaBit Port Aggregator Ease of Use • Display alternately shows link utilization, the peak utilization, and the time the peak utilization occurred, for all four ports • LED indicators show redundant power, link status, Tap or Aggregation mode, and utilization alarms • XFP monitor ports provide increased flexibility • All necessary network and monitor cables are included • Optional 19-inch rack frame holds up to two iTap Port Aggregators • Compatible with all major manufacturers’ monitoring devices,
