Through CCM Count
Indicates the number of received CCM frames whose maintenance domain level (MD level) is
higher than the MD level of the AQ1300/AQ1301
Unexpected MEP Count
Indicates the number of unexpected MEP detections
This is detected when the maintenance domain level (MD level) and domain name in the received
CCM frame are correct but the MEP ID of the other network device (MEP) is different from the “target
MEP ID.” The domain name is either Short MA Name (IEEE802.1ag standard) or MEG ID (ITU-T
Y1731 recommendation).
Mismerge Count
Indicates the number of mismerge detections
This is detected when the maintenance domain level (MD level) in the received CCM frame is
correct but the domain name is not.
Unexpected MEG Level Count
Indicates the number of unexpected MEG level detections
This is detected when the maintenance domain level in the received CCM frame is less than the
MD level of the AQ1300/AQ1301.
Unexpected Period Count
Indicates the number of unexpected period detections
This is detected when the maintenance domain level (MD level), domain name, and MEP ID in the
received CCM frame are correct but the transmission interval of the other network device (MEP) is
different from that of the AQ1300/AQ1301.
Link Down Count
Indicates the number of link-down detections
CRC Error
Indicates the number of CRC error frames that have been received
Undersize Error
Indicates the number of undersize frames (less than 64 bytes) that have been received
Alignment Error
Indicates the number of alignment error frames that have been received
Symbol Error
Indicates the number of symbol error frames that have been received
