4.2.3. State Data
YANG can model state data, as well as configuration data, based on
the “config” statement. When a node is tagged with “config false”,
its subhierarchy is flagged as state data, to be reported using
NETCONF’s operation, not the operation. Parent
containers, lists, and key leafs are reported also, giving the
context for the state data.
In this example, two leafs are defined for each interface, a
configured speed and an observed speed. The observed speed is not
configuration, so it can be returned with NETCONF operations,
but not with operations. The observed speed is not
configuration data, and it cannot be manipulated using .
list interface {
key “name”;
leaf name {
type string;
}
leaf speed {
type enumeration {
enum 10m;
enum 100m;
enum auto;
}
}
leaf observed-speed {
type uint32;
config false;
}
}
