cally when the traffi c volume falls below the receiving capacity of the NIC. 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 full-duplex link at which an alarm is triggered. For example, the
iTap Port Aggregator can warn you when the utilization in either direction passes
the 30% level. When a threshold level is exceeded, the alarm LED illuminates and
the remote interfaces record the event. The iTap Port Aggregator records the level
of the highest peak along with the date and time. Since the iTap Port Aggregator is
monitoring the utilization levels, this information is always available regardless of
the aggregation process.
Seeing is Believing
The display and alarm LEDs provide a quick visual check that the utilization
levels are not exceeding the capacity of the monitoring device or a pre-determined
threshold. From the display, you can view the current bandwidth utilization of each
side of a full-duplex link with the size and time of the highest peak. A quick check
of the display lets you know if there was an event that requires further investiga-
tion. After taking action on a utilization or peak event, you can reset the data from
a recessed reset button on the front panel or from a remote interface.
Access Information Anywhere
The Web Manager and System Manager allow you to remotely set parameters,
view status information, and monitor traffi c statistical data. These interfaces
provide security and performance information such as the number of over- and
under-sized packets, packet collisions, and CRC errors. You can remotely set the
alarm thresholds, clear the traffi c data counters, and turn on or off a Monitor Port.
This access is also available via an optional wireless link from your wireless PDA
or laptop.
Web Manager
Net Optics' Web Manager is the browser-based interface that allows you to change
settings, view status, and retrieve data remotely with simple-to-use controls. When
you access an iTap Port Aggregator with Web Manager, all confi gurations, status,
and traffi c data are displayed on a single page. Changes to the confi guration can be
made with a few clicks of the mouse.
