Hi Macro, I use following CLI command to setup SCTP server, but VPP crashed. While this command works for TCP/UDP.
Can you tell me the correct cli commands to run echo test for SCTP? vpp# set int ip address FortyGigabitEthernet18/0/1 192.168.60.73/24 vpp# set int state FortyGigabitEthernet18/0/1 up vpp# set ip arp FortyGigabitEthernet18/0/1 192.168.60.74 3c:fd:fe:c2:12:68 vpp# test echo server fifo-size 4096 uri sctp://192.168.60.73/1234 no-echo After debugging, I found it’s caused by invalid sw_if_index in sctp_connection_bind function of sctp.c.

And is there any performance report for SCTP? You can have a look at the test for SCTP: 1) test/test_sctp.py 2) src/vnet/session-apps/echo_client.c & echo_server.c The echo_client and echo_server are used by TCP / UDP and SCTP to exercise the networking stack implemented. With regards to the state-machine (I assumed that's what you're asking by "association", "packet transmssion/reception", etc.), the whole of it is gone through when running the tests. If you are interested in seeing/learning how that's implemented I am afraid you need to look into the code tho. With regards to performance: no, there're no reports. However, something can be retrieved by running the test_sctp.py since at the end it prints out how much data has been transferred and how long that took.

If yes what is the configuration for SCTP. Does it support the same features as the linux kernel SCTP ? VPP has an implementation for SCTP. You can look into /src/vnet/sctp folder to see what we currently support in terms of RFC. Any feedback (and contribution) is very much welcome!
