Configuring the Profiler to Work with RSPAN Configuration

Switched Port Analyzer (SPAN) allows you to send a copy of traffic passing through ports to another port on the switch. SPAN is important to mirror the traffic received or transmitted (or both) on one or more source ports to a destination port for analysis, such as to the Profiler. When Profiler receives the traffic, it filters out the DHCP packets and uses them for profiling devices. While SPAN mirrors ports in the same switch, RSPAN (Remote SPAN) mirrors ports on one switch to a port on different switch.

The incoming traffic passing through port Gi0/1 on Switch 1 will be mirrored to port Gi0/2 on Switch 2 and captured by the Profiler on IPS connected to port Gi0/2.
