Cisco Customer Voice Portal Lic Rt Port State
The real-time port state object is a real-time snapshot metric indicating the threshold level of port license usage. There are five levels: 'safe' Port usage is within a safe range. 'unknown' Port usage state is currently unknown. 'warning' Port usage is rising, approaching a level of concern. 'critical' Port usage is precariously close to the limit. 'failure' Port usage has reached or exceeded the maximum allowable and calls are currently being rejected. An administrator may set the required percentage of port licenses in use needed to reach a given threshold level, with the exception of the failure level which is reached when the number of ports checked out is equal to the total number of licenses ports.
