how can I make more than two flows using rest api?

sylee — Sun, 23 Nov 2014 06:18:30 GMT

I can make one flow as below

{

"flow": {
"priority": 30000,
"table_id": 200,
"idle_timeout": 60,
"match": [
{ "ipv4_src": "10.0.0.1"},
{"ipv4_dst": "10.0.0.22"},
{"ip_proto": "tcp"},
{"eth_type": "ipv4"},
{"tcp_dst": "80"}],
"instructions": [{"apply_actions": [{"output": 1}]}]
}

}

I made two flows as below but..

{

"flow": [

{
"priority": 30000,
"table_id": 200,
"idle_timeout": 60,
"match": [
{ "ipv4_src": "10.0.0.1"},
{"ipv4_dst": "10.0.0.22"},
{"ip_proto": "tcp"},
{"eth_type": "ipv4"},
{"tcp_dst": "80"}],
"instructions": [{"apply_actions": [{"output": 1}]}]
},

{
"priority": 30000,
"table_id": 200,
"idle_timeout": 60,
"match": [
{ "ipv4_src": "10.0.0.5"},
{"ipv4_dst": "10.0.0.3"},
{"ip_proto": "tcp"},
{"eth_type": "ipv4"},
{"tcp_dst": "80"}],
"instructions": [{"apply_actions": [{"output": 5}]}]
}

]

}

Hello,

How are you trying to add these flows?

Do you get an error message?

I made two examples('flow' or 'flows').

First,

------------------------------------------------------------------------------------------------------

{
"flow": [
{
"priority": 30000,
"table_id": 200,
"idle_timeout": 60,
"match": [
{ "ipv4_src": "10.0.0.1"},
{"ipv4_dst": "10.0.0.22"},
{"ip_proto": "tcp"},
{"eth_type": "ipv4"},
{"tcp_dst": "80"}],
"instructions": [{"apply_actions": [{"output": 1}]}]
},

Hello sylee,

I just received a confirmation that unfortunately adding more than one flow via the Rest API is not supported.
