This is the row-status object for adding or deleting a port-range filter entry, which can only be set to active once its associated service-type configuration is valid for that row. This follows the same creation-ordering pattern as the other filter tables in this MIB -- the underlying matching criteria must be configured before the row can be activated -- so scripted filter-policy deployment needs to respect this sequence to avoid failed activations. An admin's automation script that tries to activate a new port-range entry in the same SNMP operation as setting its port bounds, rather than in a strictly preceding step, risks the activation failing if the device processes the row-status object before the dependent value is committed.
