This read-write enumerated value records whether a network management tool configured this OCX port as fractional or clear-channel, choosing frac(1) or clear(2); it has no effect on the actual hardware configuration and exists purely as a record for management tools. Admins or management systems set it to track how a given port was provisioned for later reference, rather than to change device behavior. For example, a provisioning tool that configured this port for clear-channel service would set wfOcxConfigManagerMethod to clear(2) purely as a bookkeeping record.
