Configuration Notes
NetStream and sFlow cannot be configured on the same device.
sFlow does not support sampling of protocol packets processed by CPU.
sFlow does not support sampling for IPv6 multicast packets.
When sampling outgoing packets, the device does not record source VLAN information in the packets. The VLAN information is invalid in the flow table and command output.
sFlow sampling is on the basis of original packets. After the forwwarding behavior is modified (for example, policy routing is applied) or information about the packets to be forwarded is modified (for example, ACL or QoS is applied), the modification cannot be shown in the sFlow statistics.
