cwrHistStatus
Cisco Wireless History Status
1.3.6.1.4.1.9.9.136.1.7.1.1.15
This object represents the current state of this histogram collection. Once the histogram collection is complete the status changes statusCaptured and the data is available for use. None of the parameters of a histogram specification may be modified when the specification is in statusInProgress. A statusCaptured or statusStopped histogram must be actionClear'ed before another histogram specification may be started. The histogram may be read accurately between the cwrUpdateRate intervals. If the read spans across the update time data from the previous and current updates can be mingled.
