Hello,
Looks like HP have upgraded switch firmware to WB.15.16.0004 and OF
1.3 made possible. Now I found some information what flows can be
installed in specific tables (100 and 200 table). I modified
simple_switch_13.py. At first time it look like working when I got
notifications or errors. Switch's flow table becomes empty. Looks like
switch reconnecting after some time? Thanks in advance.
What is config and main modes?

Hi,
I’m looking for root problems why HP 2920 switch not fully functional
using 1.3 OF in Ryu controller. By the way with 1.0 OF works fine.
It’s possible to make some modifications in controller code or write
application to add 1.3 OF capability for this switch?
Regards,
Vilius.
