• Must specify which data port to send traffic (Data Port 1 or Data Port 2)
• Can have 2 simultaneous SPAN / RSPAN / VACL sessions
– Cannot mix types of sessions on same data port
• Use the 2 ports independently or together; for example:
– Dedicate one data port for reporting, the other for troubleshooting
– Break out in/out traffic by spanning to each port in one direction

Utilizing the Second Data Port on NAM-2
Besides the increased processing and memory performance of the NAM-2, it also includes a second data
port for increased flexibility when selecting data sources for monitoring. This allows for many different
possible uses including:
• Using one port for troubleshooting and dedicating the other to historical reporting
• Breaking out the traffic direction for finer granularity monitoring (one port for transmitted data, and one
port for received data)
• Increased flexibility when choosing data sources:
• 2 SPAN sessions
• 1 SPAN, 1 RSPAN
• 1 SPAN, 1 VACL
•Etc.
Note: If using 2 VACL sessions, the SPAN active window will not display any active sessions, yet data is
currently being sent to the NAM-1/2. Always review the host switch configuration to determine if any VACLs
are forwarding data to the NAM.
