Local SPAN and RSPAN Overview
Local SPAN and RSPAN both select network traffic to send to a network analyzer such as a SwitchProbe
device or other Remote Monitoring (RMON) probe. SPAN does not affect the switching of network
traffic on source ports or VLANs. SPAN sends a copy of the packets received or transmitted by the
source ports and VLANs to the destination port. You must dedicate the destination port for SPAN use.
