How to wildcard Ipv4 address?

[panluowei]

Can anyone help me with a flow definition containing a wildcarded ipv4 address in json. I thought it would be something like the following, but the HP VAN Controller (version 2.4.5.0614) returns:

{"error":"java.lang.IllegalArgumentException","message":"Bad address format: 192.168.0.0/16"}

----- flow.json ------

{

"flow": {

"priority": 30000,

"idle_timeout": 30,

"match": [

{"eth_type": "ipv4"},

{"ipv4_dst": "192.168.0.0/16"}

],

"instructions":[{

"apply_actions": [{"output": "NORMAL"}]}]

}}

Thanks!

You'd want to modify the flow JSON you're pushing to include a "mask" parameter along with the IPv4 address, as shown below:

{
  "flow": {
    "priority": 30000,
    "idle_timeout": 30,
    "match": [
      {"eth_type": "ipv4"},
      {"ipv4_dst": "192.168.0.0",
       "mask": "255.255.0.0"}
    ],
    "instructions":[{
      "apply_actions": [{"output": "NORMAL"}]
    }]
  }
}
