This object is the same change-detection mechanism as cSmeConfigTableLastChanged, but specifically for the host port table, tracked separately because host port assignments, potentially numerous, one per attached server, change independently and more often than cluster or interface configuration. Separating this from the general config-change timestamp lets a monitoring tool detect host-port churn, such as servers being added or removed from encryption, without assuming cluster-level settings also changed. This timestamp advancing while cSmeConfigTableLastChanged stays flat tells a poller that only host port mappings changed, letting it skip re-polling the larger cluster and interface tables.
