Hi Group, Should sFlow capture packets on the wire or only those packets which the device has to process? For example if the packet, ether mac is not the NIC's it will be dropped before L2 processing( assume no bridging) , but then should sFlow , packet sampling should sample this packet?
If it does the flow info would not be what is crosssing the switch. Consider a broadcast link on a switch where there is numerous crosstalk between hosts, the sFlow would send all this data as flow info, even though it has not participated in it ! Is this what the collector is interested in? BR, -Sujay
