The iTap Port Aggregator makes network
monitoring easier. The powerful combi-
nation of a permanent, passive access
point and remote monitoring of key traffic
indicators increases your management
options and speeds response to troubled
links. When an iTap Port Aggregator
indicates high utilization or CRC errors are
occurring on a critical network link, you
are given timely warning without relying
on other time-consuming tools.
The iTap Port Aggregator displays the link
utilization level in both directions in real
time, with the size and time of the last
peak, right on the front panel. The iTap
Port Aggregator is accessible from remote
interfaces that provide information and
control from anywhere in the network.
The iTap Port Aggregator gives you the
information and the passive access point
you need to respond quickly to network
events.
For greater flexibility and response speed,
use iTap Port Aggregators with Net
Optics’ SpyderSwitches and control the
deployment of your analyzers from one
point without disturbing a single network
connection.

iTap 10/100/1000BaseT Port Aggregator
Best in Aggregation
The iTap Port Aggregator combines and
regenerates both directions of a full-duplex
stream, sending all aggregated traffic out
one or two separate passive monitoring
ports. Typically, full-duplex monitoring with
a network tap requires two NICs (or a
dual-channel NIC)—one interface for each
side of the full-duplex link. Net Optics’
iTap Port Aggregator enables one or two
devices to simultaneously monitor a full-
duplex link using only one NIC per device.
After the traffic has been aggregated to
a single flow, it is no longer possible to
distinguish the utilization levels of each
side of the bi-directional link. The iTap
Port Aggregator tracks the utilization
levels before aggregation, keeping this
vital information easily accessible from its
remote and command line interfaces.
With its visual display, remote interfaces,
and well-buffered aggregation, Net Optics’
iTap Port Aggregator creates an entirely
new category of passive access devices.
