Question

You are integrating a network automation solution with a device that exposes the openconfig-interfaces YANG model. A colleague hands you the following module fragment:

container interfaces {
  list interface {
    key "name";
    leaf name { type string; }
    container config {
      leaf name { type string; }
      leaf mtu { type uint16; }
      leaf enabled { type boolean; }
      leaf description { type string; }
    }
  }
}

You must build a JSON payload to configure interface GigabitEthernet0/0/1 with an MTU of 1500, an enabled state of true, and a description of "uplink-core". Which JSON body correctly represents this configuration for the model?

Accepted Answer

{ "interfaces": { "interface": [ { "name": "GigabitEthernet0/0/1", "config": { "name": "GigabitEthernet0/0/1", "mtu": 1500, "enabled": true, "description": "uplink-core" } } ] } }

Answer

{ "interfaces": { "interface": { "name": "GigabitEthernet0/0/1", "config": { "mtu": "1500", "enabled": "true", "description": "uplink-core" } } } }
