Configuring Local SPAN and RSPAN
Source VLANs
A source VLAN is a VLAN monitored for network traffic analysis. VLAN-based SPAN (VSPAN) uses
a VLAN as the SPAN source. All the ports in the source VLANs become source ports.
Destination Ports
A destination port is a Layer 2 or Layer 3 LAN port to which SPAN sends traffic for analysis.
When you configure a port as a SPAN destination port, it can no longer receive any traffic. When you
configure a port as a SPAN destination port, the port is dedicated for use only by the SPAN feature. A
SPAN destination port does not forward any traffic except that required for the SPAN session.
With Release 12.1(13)E and later releases, you can configure trunk ports as destination ports, which
allows destination trunk ports to transmit encapsulated traffic. With earlier releases, trunk ports stop
trunking when you configure them as a destination port.
