This OID holds the Relative Name (Rn) of a local mapping entry used when resolving this policy — the single naming component that, appended to its parent's DN, distinguishes this local map instance from its sibling instances under the same parent. Monitoring software combines this Rn with the parent path to reconstruct the object's full DN, which matters when several local map instances exist side by side under the same UCS container. For example, when cucsPolicyLocalMapRn returns a short token such as "local-map", that token is concatenated onto the parent's DN to form the complete address used elsewhere in the MIB for this local map instance.
