Hello list!
I am evaluating the performance of RTnet under several load conditions. The
(so called) network consists of two cross-connected PC's with RTL8169 gigabit
NIC's.
Starting RTnet with the delivered start script is working fine, but I would
like to avoid using a RTcfg server. So I tried to produce a procedure for a
statically configured RTnet network (mostly extracted from the start script):
1) loading modules like: rtnet.ko, rtipv4.ko,....
2) `rtifconfig rtlo up 127.0.0.1`
3) loading modules: rtmac.ko and tdma.ko
4) `rtifconfig rteth0 up 10.0.0.1`
5) update routing table with rtroute, to provide a route to the other PC
6) run `tdmacfg rteth0 server 10000` on the master
7) run `tdmacfg rteth0 slave` on the slave
8) run `tdmacfg slot 0 2000` on the slave (does not return, because it starts
calibration as stated in the docu)
9) run `tdmacfg slot 0 0` on the master (does finish nearly instantly)
(If one of the above commands is syntactically wrong, it is because I am not
at the test PC at the moment and I have to dig this out of my memory.)
The command issued in step 8) does not finish, I suppose because calibration
never succeeds.
Ethereal tells me 0 sending/receiving packets, on both sides. But as far as I
can tell at least the SOF should be transmitted?
So, does anybody know what goes wrong in my setup? Or has an advice what to
change?
Best regards,
bernhard
