Hi, iperf3 setup: iperf3 server(docker app) ------------------- iperf3 client machine1 machine2
version: iperf3 server:3.5 iperf3 client: 3.1.7 start the server: iperf3 -s Trying to check TCP traffic with different TCP segments size using the flag --set-mss. Initially tried setting --set-mss more than 10k, got below response from iperf3 client. iperf3: parameter error - TCP MSS too large (maximum = 9216 bytes) So start the traffic with mss value set as 9216 bytes as below. client: iperf3 -c <server ip> --set-mss 9216 captured the sent packets and analyzed in wireshark and found most of the packets with TCP segment size has large as 29k bytes. why the --set-mss has no effect on the sent packets? Is there any other option to limit the TCP packet size?
