Understanding How Local SPAN and RSPAN Work
Local SPAN Overview
Local SPAN supports source ports, source VLANs, and destination ports on the same Catalyst 6500
series switch. Local SPAN copies traffic from one or more source ports in any VLAN or from one or
more VLANs to a destination port for analysis (see
all traffic on Ethernet port 5 (the source port) is copied to Ethernet port 10. A network analyzer on
Ethernet port 10 receives all network traffic from Ethernet port 5 without being physically attached to
Ethernet port 5.
