On a Definition object -- a network-control policy definition that governs discovery-protocol and uplink-failure behavior for a vNIC/vHBA template or service profile -- cucsNwctrlDefinitionIntId is a text (SnmpAdminString) field holding an internal identifier string UCS Manager assigns to this network-control policy definition. An admin reads this string because it carries the actual identifying detail -- not just an internal numeric ID -- needed to make sense of that specific Definition instance. For example, an admin reviewing Definition entries would look at cucsNwctrlDefinitionIntId to see the concrete value rather than a bare object reference.
