Hi.
I am trying to stress test my system running the latest 6.4.2 DPK version.
Considering that the M3UA license is running with: SS7SBHSTM3UAN , 39,328kb/s
I'm trying to run back to back with 2 hosts and a single SNLINK defined, and I am getting very fast the following congestion errors:
S7L:I0000 SCTP Congestion Status: assoc_id=0 Unknown (0x 2)
MBM Rx: M-I0000-t02e2-i0000-fd2-dc2-s06

Attached the config.txt:
CNSYS:IPADDR=192.168.10.26,PER=0,DAUD=Y;
SNSLI:SNLINK=1,IPADDR=192.168.10.71,SNEND=C,HPORT=2905,PPORT=2905,SNTYPE=M3UA,SS7MD=ANSI;
SNAPI:AS=1,OPC=0x0e61,RC=1,TRMD=LS,SS7MD=ANSI;
SNRAI:RAS=1,RC=1,DPC=0x0664;
SNALI:SNAL=1,RAS=1,SNLINK=1;
SNLBI:SNLB=1,AS=1,RAS=1;
MTP_USER_PART 0x03 0x33
My question is, what am I doing wrong ? Do I have to run against multiple hosts ? Do I need to define more SNLINKs ? Where is the limitation ?
The network card throughput shows a very low and little bandwidth usage, even when copying a file the usage is higher.
Any ideas ? I tried to play will all kind of parameters in SCTP , increasing SCTP buffers and NUM_MSGS in system.txt but nothing.
Thank you.
