One of the most difficult challenges facing Security, VoIP, and Network Management Solutions is how to implement network tools onto enterprise networks. Enterprise networks are becoming more complex when looking at how to monitor and capture data. It can be difficult or impossible to gain access to network SPAN Ports or inserting In-line Devices like Intrusion Prevention Systems into enterprise networks. Contention for network access is a major problem. Learn how to design a network access solution that meets the requirements for security, network monitoring, and overall network access solutions. We help solve the questions, How do I get secure access to the network for capturing data or monitoring data traffic? Why TAP your network?

How do I connect my Network Tool?
• Brief History
It’s simple, I need
access to the data!

How do I connect my Network Tool?
• How are Network Tools Deployed?
– SPAN or Mirrored Ports (switches)
– TAP – Test Access Port
– In-Line Appliances

SPAN / Mirrored Switch Port
• Mirrored Port or Cisco Term SPAN (Switch Port Analyzer)
– With SPAN, traffic from any port on the network switch can be
mirrored or copied to another port, which is designated as the SPAN
port. You can then connect the SPAN port to the Network Tool

Switch
SPAN Port

SPAN / Mirrored Switch Port
• Benefits • Limitations
– Internal Switch Traffic
– Contention for SPAN Ports
Visible
• Network Engineers, Security, VoIP,
– VLAN’s are Visible
etc
• I have no SPAN Ports Available
– Monitoring device is missing packets due
to port over-subscription
– Degraded network switch performance
when monitoring a busy segment
– Cannot view physical layer 1 & 2 errors
– Full duplex monitoring is not available
– Requires re-configuration of the network
switch
• Authorization Problems
• Switch Configuration Errors can
cause major Network Problems
