#23 iperf udp server does not print output

[Anonymous]

Hi all,
We are using Iperf (version 2.0.5) in our test setup and we are seeing a strange problem as below.
The server and client udp commands used in our testing as follows
Command for PDN Iperf (Server): D:\Iperf\iperf.exe -s -u -i 1 -f m -B 10.203.194.192
Command for UE Iperf (Client): E:\Iperf\iperf.exe -c 10.203.194.192 -B 18.19.20.2 -u -b 40.0M -t 60 -f m

Now, the server starts listening on port 5001, once the client started, it sends says, connected to server and sends the packets (as per the print output). However, the server side doesn't print packets, although in wireshark, on 5001 port, there are udp packets received.

Server Response:
------------------------------------------------------------
Server listening on UDP port 5001
Receiving 1470 byte datagrams
UDP buffer size: 0.01 MByte (default)
------------------------------------------------------------

Anybody facing this type of problem? if yes, how to rectify this or is it a defect in iperf.exe?

:hello , do you resolve the problem ? because i have the same :(
Try to make the udp checksum bytes 0,so that OS forwards it to the transport layer
