Local SPAN, RSPAN, and ERSPAN Overview

Local SPAN, RSPAN, and ERSPAN sessions allow you to monitor traffic on one or more ports, or one
or more VLANs, and send the monitored traffic to one or more destination ports. You can configure
per-VLAN filtering on destination trunk ports.
Local SPAN, RSPAN, and ERSPAN all send traffic to a network analyzer such as a SwitchProbe device
or other Remote Monitoring (RMON) probe. SPAN does not affect the switching of 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.
