The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter includes the following sections:
Traffic monitoring copies traffic from one or more sources and sends the copied traffic to a dedicated destination port for analysis by a network analyzer. This feature is also known as Switched Port Analyzer (SPAN).
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.
An Ethernet traffic monitoring session can monitor any of the following traffic sources:
A Fibre Channel traffic monitoring session can monitor any of the following traffic sources:
Note |
This procedure describes how to create an Ethernet traffic monitoring session. To create a Fibre Channel monitoring session, select the SAN tab instead of the LAN tab in Step 2. |
You can choose multiple sources from more than one source type to be monitored by a traffic monitoring session. The available sources depend on the components configured in the Cisco UCS instance.
Note |
This procedure describes how to add sources for Ethernet traffic monitoring sessions. To add sources for a Fibre Channel monitoring session, select the SAN tab instead of the LAN tab in Step 2. |
A traffic monitoring session must be created.
Step 1 | In the Navigation pane, click the LAN tab. |
Step 2 | On the LAN tab, expand . |
Step 3 | Expand Fabric_Interconnect_Name and click the monitor session that you want to configure. |
Step 4 | In the Work pane, click the General tab. |
Step 5 | In the Sources area, expand the section for the type of traffic source that you want to add. |
Step 6 | To see the components that are available for monitoring, click the + button in the right-hand edge of the table to open the Create Monitoring Session Source dialog box. |
Step 7 |
Select a source component and click OK. You can repeat the preceding three steps as needed to add multiple sources from multiple source types. |
Step 8 | Click Save Changes. |
Activate the traffic monitoring session. If the session is already activated, traffic will be forwarded to the monitoring destination when you add a source.
Note |
This procedure describes how to activate an Ethernet traffic monitoring session. To activate a Fibre Channel monitoring session, select the SAN tab instead of the LAN tab in Step 2. |
A traffic monitoring session must be created.
Step 1 | In the Navigation pane, click the LAN tab. |
Step 2 | On the LAN tab, expand . |
Step 3 | Expand Fabric_Interconnect_Name and click the monitor session that you want to activate. |
Step 4 | In the Work pane, click the General tab. |
Step 5 | In the Properties area, click the enabled radio button for Admin State. |
Step 6 | Click Save Changes. |
If a traffic monitoring source is configured, traffic begins to flow to the traffic monitoring destination port.
Note |
This procedure describes how to delete an Ethernet traffic monitoring session. To delete a Fibre Channel monitoring session, select the SAN tab instead of the LAN tab in Step 2. |
Step 1 | In the Navigation pane, click the LAN tab. |
Step 2 | On the LAN tab, expand . |
Step 3 | Expand Fabric_Interconnect_Name and click the monitor session that you want to delete. |
Step 4 | In the Work pane, click the General tab. |
Step 5 | In the Actions area, click the Delete icon. |
Step 6 | If Cisco UCS Manager GUI displays a confirmation dialog box, click Yes. |
