Remote Management
The Net Optics Web Manager and System
Manager software interfaces allow IT man-
agers to remotely view status information,
set threshold values, and monitor traffic
statistics from our products. These software
interfaces can display the number of over-
and under-sized packets, packet collisions
and peak rates. Alarms can be set and
counters reset remotely. To eliminate the
possibility of unauthorized personnel using
the Span Port Aggregator to gain access to
When the threshold value is exceeded, a
record is viewable via the management
interfaces and the front panel LED. The
management interface tracks the level of
the highest peak, date and time.
Buffering Bursts
When traffic levels
exceed the capacity
of the receiving NIC,
some products may
lose valuable infor-
mation. The iTap Port
Aggregator stores the
overflow traffic in buffer memory, ensuring
proper operation and statistics. The buffers
automatically clear when traffic volume
falls below acceptable levels, allowing
the Aggregator to absorb bursts without
packet loss. For high-load links, 1 GB of
memory is available.

The front panel display and alarm LEDs
provide a quick visual display for real-
time utilization levels and pre-determined
threshold values. When trouble-shooting,
utilization statistics for each Span Port
can also be viewed. The IT engineer
gains valuable insight without the need
for extra computers, cables and power
outlets. A quick check of the display
provides enough information in the event
further investigation is required.
After taking action on an alert, values
can be reset while logged into the com-
mand line interface (CLI) and pressing a
front panel “reset” button. These values
can also be reset via Net Optics man-
agement interfaces.
Security and Access
An available feature allows IT managers
to limit access as well. Data on the front
panel can be shown or not, and access
to the rear panel management port can
be enabled or disabled, prohibiting
unauthorized access. The monitor ports
can also be remotely changed to allow
or prevent access.
iTap Port Aggregators form an early warning
system to detect network anomalies.
