Definitions: 'missingPkt'(0) - While playing out a sequence of packets, at least one packet was determined to be missing based on a gap in the CEP sequence number. Note: If the implementation supports packet reordering, detecting gaps SHOULD take place as they are played out, not as they arrive. This provides time for misordered packets to arrive late. 'ooRngDropped'(1) - At least one packet arrived outside the range of the jitter buffer. This may be because the jitter buffer is full or the sequence number addresses a buffer outside the current jitter buffer range or an already occupied buffer within range. Whether or not packet reordering is supported by the implementation, this indication MUST be supported. 'jtrBfrUnder'(2) - The jitter buffer underflowed because not enough packets arrived as packets were being played out. 'pktMalformed'(3) - Any error related to unexpected packet format (except bad header stack) or unexpected length. 'lops'(4) - Loss of Packet Synchronization. 'cepRdi'(5) - Circuit Emulation over Packet Remote Defect Indication. Remote Defect Indication (RDI) is generated by the remote CEP de-packetizer when LOPS is detected. 'cepAis'(6) - Remote CEP packetizer has detected an Alarm Indication Signal (AIS) on its incoming SONET stream. cepAis MUST NOT (in itself) cause a CEP PW down notification. 'badHdrStack'(7) - Set when the number of CEP header extensions detected in incoming packets does not match the expected number. 'cepNeFailure'(8) - Set when CEP-NE failure is currently declared. 'cepFeFailure'(8) - Set when CEP-FE failure is currently declared. This object MUST hold the accumulated indications until the next SNMP write that clear the indication(s). Writing a non-zero value MUST fail. Currently, there is no hierarchy of CEP defects. The algorithm used to capture these indications is implementation specific.
