The interface configuration allows users to configure information about ports of devices connected to the system. The information can be used by ONOS and its applications to drive certain behaviors.

Basic definitions

  • Ports represent physical ports of devices connected to ONOS. They act as containers of one or more interfaces that actually hold the real configuration
  • Interfaces are subset of physical ports distinguished by different parameters, such as i.e. VLANs, IPs, MAC addresses

Configuration structure

Following is reported a typical interface configuration used for SDN-IP

Example of interface configuration
{
    "ports" : {
        "of:0000000000000001/1" : {
            "interfaces" : [
                {
                    "name" : "Interface 1 sw 1",
                    "ips"  : [ "1.1.1.1/24", "10.10.10.1/24" ],
                    "mac"  : "00:00:00:00:00:01"
                }
            ]
        },
        "of:0000000000000002/1" : {
            "interfaces" : [
                {
                    "name" : "Interface 1 sw 2",
                    "ips"  : [ "2.2.2.2/24" ],
                    "mac"  : "00:00:00:00:00:02"
                },
				{
                    "name" : "Interface 2 sw 2",
                    "ips"  : [ "3.3.3.3/24" ],
                    "mac"  : "00:00:00:00:00:03"
                }
            ]
        }
}

Interfaces

1 to 1 mapping between an interface and a port

Configurations attributes written directly under a physical port won't be parsed. In case you like to apply a specific configuration to an entire physical port, just add one interface to it and specify inside its parameters.
