This variable indicates the current status of the path payload with a bit map that can indicate multiple defects at once. The bit positions are assigned as follows: etherWisPathLOP(0) This bit is set to indicate that an LOP-P (Loss of Pointer - Path) defect is being experienced. Note: when this bit is set, sonetPathSTSLOP MUST be set in the corresponding instance of sonetPathCurrentStatus. etherWisPathAIS(1) This bit is set to indicate that an AIS-P (Alarm Indication Signal - Path) defect is being experienced. Note: when this bit is set, sonetPathSTSAIS MUST be set in the corresponding instance of sonetPathCurrentStatus. etherWisPathPLM(1) This bit is set to indicate that a PLM-P (Payload Label Mismatch - Path) defect is being experienced. Note: when this bit is set, sonetPathSignalLabelMismatch MUST be set in the corresponding instance of sonetPathCurrentStatus. etherWisPathLCD(3) This bit is set to indicate that an LCD-P (Loss of Codegroup Delination - Path) defect is being experienced. Since this defect is detected by the PCS and not by the path layer itself, there is no corresponding bit in sonetPathCurrentStatus.
