RSPAN VLANs and source and destination
switches
You can configure a VLAN as a remote switched port analyzer (RSPAN) VLAN. RSPAN
lets you mirror traffic from multiple source ports (or from all ports that are members of
a VLAN) from different network devices and send the mirrored traffic to a destination
port (a probe port connected to a network analyzer) on a remote device. The mirrored
traffic is tagged with the RSPAN VLAN ID and transmitted over trunk ports in the RSPAN
VLAN.
A switch can function as an RSPAN source switch that sends traffic to another switch
that functions as an RSPAN destination switch. Because the switch supports multiple
RSPAN configurations, the switch can also function as an RSPAN destination switch that
receives traffic from another switch that functions as an RSPAN source switch.
