35 FW-1216 Probable Cause Indicates that the number of link resets that the port experiences has changed from a value outside of the acceptable range to a value within the acceptable range. Link resets occur due to link timeout errors that indicate no frame activity at all. Both physical and hardware problems can cause link resets to increase. Recommended Respond to this message as is appropriate to the particular policy of the end-user installation. Action Severity INFO FW-1216 Message , [FW-1216], ,, INFO, , , value has changed(High=, Low=). Current value is . Probable Cause Indicates that the number of arbitrated loop physical address (AL_PA) cyclic redundancy check (CRC) errors has changed. This indicates that errors have been detected in the FC frame. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment, temperature fluctuations, and aging equipment. Recommended Action Verify that your optical components are clean and function properly. Replace deteriorating cables or small form-factor pluggables (SFPs). Check for damage from heat or age. You should set your high boundaries to five- or six-digit figures, as only large numbers of messages indicate a problem in this area. Severity INFO FW-1217 Message , [FW-1217], ,, INFO, , , is below low boundary(High=, Low=). Current value is . Probable Cause Indicates that the number of arbitrated loop physical address (AL_PA) cyclic redundancy check (CRC) errors has fallen below the low boundary. This indicates that errors have been detected in the FC frame. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment, temperature fluctuations, and aging equipment. You should set your high boundaries to five- or six-digit figures, as only large numbers of messages indicate a problem in this area. A low level of invalid CRC errors means that the switch is functioning normally. Recommended No action is required. Respond to this message as is appropriate to the particular policy of the Action end-user installation. Severity INFO 252 Fabric OS Message Reference 53-1001157-01
