This read-create Integer32, restricted to 0 or 5 through 10 minutes, sets how often Inverse ARP request frames are sent for a PVC address map, and is forced to 0 whenever the map's hpnicfAtmDxiMapType is not inarp. Admins tune this to control how frequently the router re-resolves the peer's Layer 3 address dynamically over the PVC, balancing timely address updates against control-plane overhead. For example, leaving this at its default of 10 minutes means an inarp-type map re-sends its Inverse ARP request every 10 minutes to refresh the peer IP-to-PVC binding.
