sFlow and Source IP Address

When the sFlow packet is sent to the sFlow collector, by default, the IP address of the outgoing interface is used in the sFlow datagram.

However, you can specify the source interface, from which the IP address is selected for the sFlow datagram, using the sflow source command. The Ethernet, VE, or loopback interface can be configured as the source interface for both IPv4 and IPv6 addresses.
