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.
