sFlow technology with VXLAN

Junos OS support sFlow technology with VXLAN. sFlow is a monitoring technology for high-speed switched or routed networks. The sFlow agent performs packet sampling and gathers interface statistics, and then combines the information into UDP datagrams that are sent to sFlow collectors.
Keep the following points in mind:

• True egress sampling is not supported on the switches. Egress sampling is done at the end of the ingress pipeline, and so the egress samples do not contain modifications that are made to the packet in the egress pipeline. When the packet flow is from the access port to the network port, sFlow is configured on the egress network port, and thus packets are captured without VXLAN encapsulation at the collector.
• Egress sampling for BUM traffic is not supported.
• Extended router data with next-hop information is not supported on the switches.
• Sampling on ingress interfaces does not capture CPU-bound traffic.
• You cannot configure sFlow on a (LAG), but you can configure it individually on a LAG member interface.
• You must not configure sFlow for more than one logical interface on a physical interface.
