Traffic Monitoring
Traffic monitoring copies traffic, from one or more source ports, and sends it to a dedicated destination port for analysis by a network analyzer. This feature is also known as Switched Port Analyzer (SPAN).
Important |
For FC port channels on Cisco UCS 6200 Fabric Interconnects, you can monitor only egress traffic. For FC port channels on Cisco UCS 6300 Fabric Interconnects, you can monitor only ingress traffic. |
Traffic Monitoring Session Types
When you create a traffic monitoring session, you can choose either an Ethernet or Fibre Channel destination port to receive the traffic. The type of destination port determines the type of session, which in turn determines the types of available traffic sources. For an Ethernet traffic monitoring session, the destination port must be an unconfigured physical port. For a Fibre Channel traffic monitoring session, the destination port must be a Fibre Channel uplink port.
Note |
For Cisco UCS 6300 Fabric Interconnects, the destination port must also be an unconfigured physical Ethernet port. For Cisco UCS 6332 and Cisco UCS 6332-16UP Fabric Interconnects, you cannot choose Fibre Channel destination ports, but can use unconfigured ethernet ports as a destination for FC traffic monitoring sessions. |
Traffic Monitoring Across Ethernet
An Ethernet traffic monitoring session can monitor any of the following traffic source and destination ports:

Destination Ports |

Traffic Monitoring for UCS 6300 Interconnects
- Cisco UCS 6300 Fabric Interconnect supports port-based mirroring.
- Cisco UCS 6300 Fabric Interconnect supports VLAN SPAN only in the receive (rx) direction.
- Ethernet SPAN is port based on the Cisco UCS 6300 Fabric Interconnect.
Traffic Monitoring for UCS 6200 Interconnects
- Cisco UCS 6200 and 6324 supports monitoring traffic in the transmit (tx) direction for up to two sources per Fabric Interconnect.
- Cisco UCS 6200 SPAN traffic is rate-limited by the SPAN destination port speed. This can be either 1 Gbps or 10 Gbps.
Traffic Monitoring Across Fibre Channel
You can monitor Fibre Channel traffic using either a Fibre Channel traffic analyzer or an Ethernet traffic analyzer. When Fibre Channel traffic is monitored with an Ethernet traffic monitoring session, the destination traffic is FCoE. The Cisco UCS 6300 Fabric Interconnect supports FC SPAN only on the ingress side. You cannot configure a Fibre Channel port on a Cisco Cisco UCS 6248 Fabric Interconnect as a source port.
A Fibre Channel traffic monitoring session can monitor any of the following traffic source and destination ports:
