是否可以使YANG列表名称可配置？

Question

I have this configuration file where dps can have a list of switches (eg sw1, sw2, etc) each switch has db_id and list of interfaces as shown below. I want to write a YANG model for this fils.

dps:
    <sw1>:
        dp_id: <value>
        interfaces:
            1:
                name: <value>
                native_vlan: <value>
            2:
                name: <value>
                native_vlan: <value>
    <sw2>:
        dp_id: <value>
        interfaces:
            1:
                name: <value>
                native_vlan: <value>
            2:
                name: <value>
                native_vlan: <value>

I could not find a way to make the inner list name (ie sw1, sw2) configurable (ie inserted by users). Is it possible or YANG doesn't support that.

Answer 1

Not possible. All list entries have the same name and are uniquely identified via their keys (in JSON encoding, the list is even represented as a single JSON array of objects). You should name your list sw , and have your users configure their name key leaf.

list sw { key name; leaf name { type string; } }

The list's name is the only way to bind an instance (a list entry) to the model definitions.
