[Iperf-users] Iperf overhead of the target bandwidth

[Jannis Ohms]

If I specify a target bandwidth like 10M which layers PDU is used as a reference?
dose Iperf generate 10 Mbit/s of UDP packets or 10 Mbit/s of Ethernetframes?
Is there a way i could estimate the bandwidth on L2

[Bob McMahon]

All the bandwidth targets are based upon the UDP payload, i.e. it's
application to application throughput. To adjust for L2 you'll need to
figure out the bytes required for L3 and L2 as well as the packet rate and
compute from there. Iperf itself doesn't know anything about the
underlying L2 framing as an example.
