Description: Indicate the error state of this entity object. Now it only supports Port, general power supply, RPS power supply and board/Subcard. It may have one of these values. The following four values can be used for all kinds of entities.

notSupported(1) means this entity cannot support this function. normal(2) means the statement of this entity is normal. for ports, it doesn't differentiate 10M/s, 100M/s, 1000M/s, duplex and half-duplex. For fan, power supply and board-Subcard, it means their states are normal. postFailure(3) means the entity fails to POST. entityAbsent(4) means the entity is absent now.

The following values is depended on the entity.

For Port entities, it may have the following values. If its POST is failure, then the value of the instance will be postFailure(3), otherwise the value will be normal(2).

If enable power supply over Ethernet on this port is failure, the value of this instance will be poeError(11), otherwise it will be normal(2).

For stack port, if it connects to another stack port normally, and these two units merge into one stack, then the value of this instance will be normal(2). If something wrong occurs and the unit cannot merge into stack, the value of this instance will be stackPortFailed(23). If the stack port forms resilient daisy chain with another stack port on the other unit, the value of this instance will be stackPortBlocked(22).

For SFP ports, if it fail to receive, the value of this instance will be sfpRecvError(31), if it fail to send, the value is sfpSendError(32), if it fail to send and receive, the value is sfpBothError(33), otherwise it will be normal(2).

fanError(41) means that the fan stops working.

psuError(51) means that the Power Supply Unit is in the state of fault.

rpsError(61) means the RPS is in the state of fault.

moduleFaulty(71) means the Module is in the state of fault.

sensorError(81) means the sensor is in the state of fault.

hardwareFaulty(91) means the hardware of specified entity is in the state of fault.

NMS must be compatible with the states which may be added in the future.
