But then it will never be applied because you never have a node called 'ethernet-port' since you have more than 1 child node. You need this under 'patternProperties' and 'additionalProperties: true' instead. And please test some of the requirements here. Like a reg value of 3 or remove 'phy-mode'. > + > + properties: > + reg: > + items: > + - enum: [1, 2] > + description: MTIP L2 switch port number > + > + required: > + - reg > + - label > + - phy-mode > + - phy-handle
