Tailf command to reset the configuration under sub-containers

YANG
1

Hi All,

I have provided my Yang Tree below for reference.

I want to remove the configuration of Container B when I configure Container A → address (or) ipv6. I tried using tailf:cli-recursive-delete; which woks only for the leaves under a container . My requirement is to reset the container B when A is configured. Kindly suggest any tailf command for the same.

    container A {
      tailf:cli-reset-container;
      tailf:cli-recursive-delete;
      container address {
        presence "true";
        tailf:cli-reset-container;
        leaf ipv6 {
          type empty;
        }
      }
      container B {
        presence "true";
        tailf:cli-reset-container;
        leaf id {
          tailf:cli-drop-node-name;
          type string;
        }
      }
   }

your excerpt does not have the trailing closing brace, and it’s a bit unclear whether container B is sibling of container A, or it is its child… can you clarify?

Hi Joseph,

Yes Container B is a child of Container A. I have correct the closing bracket on the above thread.
Kindly let us know how can we reset the config.

If i understood your expected behavior correctly, i think the YANG’s “choice” statement might do what you need (no reset annotations needed).

Below YANG implies that at any time, there can be only of of the “address” / “B” present inside of A container.
If user configures the other option, previous one is automatically “removed”.

Please test the following and see whether it works correctly:

  container A {
    choice address-or-B {
      case option-address {
        container address {
          presence "true";
          leaf ipv6 { type empty; }
        }
      }
      case option-B {
        container B {
          presence "true";
          leaf id { type string; }
        }
      }
    }
  }

(“address-or-B” / “option-…” are not visible in CLI / NETCONF messages as extra keywords of course)
