Chapter 20 Configuring SPAN
Information About SPAN Destinations
• Can be any port type: Ethernet, virtual Ethernet, Fibre Channel, virtual Fibre Channel, Port Channel,
SAN-Port Channel, VLAN, and VSAN.
• Cannot be monitored in multiple SPAN sessions.
• Cannot be a destination port.
• Each source port can be configured with a direction (ingress, egress, or both) to monitor. For VLAN,
VSAN, Port Channel, and SAN-Port Channel sources, the monitored direction can only be ingress
and applies to all physical ports in the group.
• Source ports can be in the same or different VLANs or VSANs.
• For VLAN or VSAN SPAN sources, all active ports in the source VLAN or VSAN are included as
source ports.
• The switch supports a maximum of two egress SPAN source ports.
Information About SPAN Destinations
SPAN destinations refer to the interfaces that monitors source interfaces. The Nexus 5000 Series switch
supports Ethernet and Fibre Channel interfaces as SPAN destinations.
Note Device Manager does not support the configuration of Ethernet interfaces as destination ports.
Characteristics of Destination Ports
Each local SPAN session must have a destination port (also called a monitoring port) that receives a copy
of traffic from the source ports, VLANs, or VSANs. A destination port has these characteristics:
• Can be any physical port: Ethernet, Ethernet (FCoE), or Fibre Channel. Virtual Ethernet and virtual
Fibre Channel ports cannot be destination 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
session.
