You can configure IPFIX profiles for switches.
- From your browser, log in with admin privileges to an NSX Manager at https://nsx-manager-ip-address.
- Select from the navigation panel.
- Click the Switch IPFIX Profiles tab.
- Click Add to add a profile.
Setting Description Name and Description Enter a name and optionally a description. Active Timeout (seconds) The length of time after which a flow will time out, even if more packets associated with the flow are received. Default is 300. Idle Timeout (seconds) The length of time after which a flow will time out, if no more packets associated with the flow are received (ESXi only, KVM times out all flows based on active timeout). Default is 300. Max Flows The maximum flows cached on a bridge (KVM only, not configurable on ESXi). Default is 16384. Sampling Probability (%) The percentage of packets that will be sampled (approximately). Increasing this setting may have a performance impact on the hypervisors and collectors. If all hypervisors are sending more IPFIX packets to the collector, the collector may not be able to collect all packets. Setting the probability at the default value of 0.1% will keep the performance impact low. Observation Domain ID The observation domain ID identifies which observation domain the network flows originate from. Enter 0 to indicate no specific observation domain. Collector Profile Select a switch IPFIX collector that you configure in the previous step. Priority This parameter resolves conflicts when multiple profiles apply. The IPFIX exporter will use the profile with the highest priority only. A lower value means a higher priority.
- Click Applied To to apply the profile to one or more objects.
The types of object are logical ports, logical switches, and NSGroups. If you select an NSGroup, it must contain one or more logical switches or logical ports. If the NSGroup contains only IP sets or MAC sets, it will be ignored.
