Hi everyone,

Yes, as a matter of fact, on Floodlight ACL choosing UDP protocol is
translated into 11. Is that decimal or hex ?
There might be a confusion though ! 0x11 = 17 (dec)
And Since I'm using SIP on default 5060 port shall I precise it ?

In addition, I tried adding the flow on the switch manually using dpctl
commands as below :

# sudo dpctl add-flow unix:/var/run/dp0.sock
in_port=*,dl_vlan=*,dl_src=*,dl_dst=*,dl_type=*,nw_src=192.168.2.2,nw_dst=*,nw_proto=17,tp_src=*,tp_dst=5060,icmp_type=*,icmp_code=*,actions=

I get :

# sudo dpctl dump-flows unix:/var/run/dp0.sock
stats_reply (xid=0x54e91f95): flags=none type=1(flow)
  cookie=0, duration_sec=1s, duration_nsec=552000000s, table_id=0,
priority=32768, n_packets=0, n_bytes=0,
idle_timeout=60,hard_timeout=0,actions=

And packets are blocked ! but can't get why the flow rule doesn't exactly
match the rule added !

Thanks in advance for your help !

Kind Regards,
Hssan
