Hello ryu-devel-mailinglist,
I use Mininet with a custom topology and the RYU-REST controller
"ofctl-rest.py". After installing some flowentries in the switches,
sending some packets over the network and capturing traffic I recognize
that the switches do not decrease the ttl - field in the ip - layer. I
figure out that i have to tell the switches to decrease the ttl field
(this is possible since OpenFlow - version 1.1). To do so I try the line
"type": "DEC_NW_TTL", but it does not work. My compleate command look
like this:
curl -X POST -d '{
"dpid": 1,
"cookie": 1,
"cookie_mask": 1,
"table_id": 0,
"idle_timeout": 3600,
"hard_timeout": 3600,
"priority": 0,
"flags": 1,
"match":{
"in_port": 1
},
"actions":[
{
"type":"OUTPUT",
"port": 4,
"type":"DEC_NW_TTL"
}
]
}' http://localhost:8080/stats/flowentry/add
What do I wrong? How do I have to modify the comand to let the switch
reduce ttl? Please help me.
Thank you in advance.
