(EntityPhysicalIndex=786437, UsagePhysicalIndex=786437, UsageTpye=0, UsageIndex=0, TrapSeverity=5, TrapProbableCause=549, TrapEventType=2, EntityPhysicalName=GigabitEthernet12/0/0, TrapRelaRes=Crc error, UsageValue=60, UsageUnit=1, UsageThreshold=1)

Then has meesage about high temperature for xfp module:

Jun 18 2013 12:20:26 ATS-56_ME60_2 %%01SRM/4/ESFP_TXBIAS_HIGH(l):-Slot=0; The ESFP's TxBias of slot 12 PIC 0 Port 0 is too high, please check and change a new one.
Jun 18 2013 12:20:26 ATS-56_ME60_2 %%01SRM/4/ESFP_TEMP_HIGH(l):-Slot=0; The ESFP's temperature of slot 12 PIC 0 Port 0 is too high, please check and change a new one.

Then information that crc error was resumed:

Jun 18 2013 12:20:36 2013 OREN_ATS-56_ME60_2 BASETRAP/4/CRCERRORRESUME:Slot=0;OID 1.3.6.1.4.1.2011.5.25.129.2.5.8 Port crc error alarm resumes.
