• Can be any physical port, Ethernet, Ethernet (FCoE), or Fibre Channel, and virtual Fibre Channel ports
• Cannot be a source port.
• Cannot be a port channel or SAN port channel group.
• Does not participate in spanning tree while the SPAN session is active.
• Is excluded from the source list and is not monitored if it belongs to a source VLAN of any SPAN
• Receives copies of sent and received traffic for all monitored source ports. If a destination port is
