UCS Netflow Exporter Best Practice

[CiscoMedMed]

I was trying to setup netflow in UCS but ran into some questions. When creating the exporter interface, what is a reasonable VLAN to choose? Would it be good to use the management VLAN of the UCS management - in the same subnet as the Fabric interconnects? And for the source IP would it be best practice to use the IP address of FI A and FI B respectively? Or should I select an unused set of IPs from the same subnet?

Hi,

you can choose vlan of your choice, as far as i know will have to create exporter interface for every VLAN as we can only select one while defining the exporter profile.

And for the source IP would it be best practice to use the IP address of FI A and FI B respectively? Or should I select an unused set of IPs from the same subnet? Both are valid options. you can select either one of them.

Defining the Exporter Profile

Procedure

---

Step 1	In the Navigation pane, click LAN.
Step 2	On the LAN tab, expand LAN > Netflow Monitoring > Flow Exporters > Flow Exporter Profiles.
Step 3	Click Flow Exporter Profile default.
Step 4	In the Properties area, to the side of the Exporter Interface(s) table, click Add.
Step 5	In the Create Exporter Interface dialog box, complete the following fields: Name Description VLAN Choose the VLAN that you want to associate with the exporter interface, or click Create VLANs to create a new one. PVLAN and local VLANs are not supported. All VLANs must be public and must be common to both fabric interconnects. Fabric A Source IP The source IP for the exporter interface on fabric A. Important: Make sure the IP address you specify is unique within the Cisco UCS domain. IP address conflicts can occur if you specify an IP address that is already being used by Cisco UCS Manager. Fabric A Subnet Mask The subnet mask for the exporter interface on fabric A. Fabric B Source IP The source IP for the exporter interface on fabric B. Important: Make sure the IP address you specify is unique within the Cisco UCS domain. IP address conflicts can occur if you specify an IP address that is already being used by Cisco UCS Manager. Fabric B Subnet Mask The subnet mask for the exporter interface on fabric B.
Step 6	Click OK.
