Span Port Aggregation
Monitoring individual Span Ports is made
easy with the iTap 10/100/1000 (Triple-
speed) Span Port Aggregator. By consoli-
dating Span Ports into the aggregator, IT
professionals gain valuable information
and control from a centralized device.
Benefits include improved information
visibility, responsiveness and manage-
ment efficiency. Network analysis devices
connected to the monitor ports will also
track layer 1 and 2 errors that Span Ports
may drop due to overhead.
Intelligent Tap Technology
This new iTap enabled Port Aggregator
offers a combination of powerful utili-
zation statistics tracking, internal buffering
techniques, security features and remote
management capability. Key indicators
can now be viewed from anywhere in
the organization via two new Net Optics
management tools.

Trafc Statistics
The iTap Port Aggregator combines
and regenerates traffic from up to two
Span Ports, sending all traffic to either
one or two separate monitor ports. iTap
intelligence tracks individual Span Port
statistics before it’s aggregated, keeping
this information easily accessible from
either the remote or built-in interfaces.
Threshold values can also be set for each
port to trigger alarms. For example, IT can
be alerted to utilization bursts that exceed
35% on the link for either port.
