Fabric Manager Tools and CLI Commands Chapter 1 Troubleshooting Overview Send document comments to [email protected]. Source Ports A source port, also called a monitored port, is a switched interface that you monitor for network traffic analysis. The switch supports any number of ingress source ports (up to the maximum number of available ports on the switch) and any number of source VLANs or VSANs. A source port has these characteristics: • Can be of 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. The rx/tx option is not available for VLAN or VSAN SPAN sessions. • Beginning with Cisco NX-OS Release 5.0(2)N1(1). Port channel and SAN port channel interfaces can be configured as ingress or egress source ports. • 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 Cisco Nexus 5010 switch supports a maximum of two egress SPAN source ports. This limit does not apply to the Cisco Nexus 5020 Switch and the Cisco Nexus 5548 switch. SPAN Destinations SPAN destinations refer to the interfaces that monitors source ports. The Cisco Nexus 5000 Series switch supports Ethernet and Fibre Channel interfaces as SPAN destinations.

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. 1-10 Cisco Nexus 5000 Series Troubleshooting Guide OL-25300-01
