25 FW-1217 Probable Cause Recommended Action Severity Indicates that the number of AL_PA 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. Verify that your optical components are clean and function properly. Replace deteriorating cables or 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. INFO FW-1217 Message , [FW-1217], ,, INFO, , , is below low boundary(High=, Low=). Current value is . Probable Cause Recommended Action Severity Indicates that the number of AL_PA 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. No action is required. Respond to this message as is appropriate to the particular policy of the end-user installation. INFO FW-1218 Message , [FW-1218], ,, WARNING, , , is above high boundary(High=, Low=). Current value is . Probable Cause Recommended Action Indicates that the number of CRC errors has risen above the high 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 configure a five- or six-figure high boundary for this area. Only five-figure (or higher) values for CRC errors indicate problems. When an "above" message is received, check for a faulty cable or deteriorated SFP. Replace the cable or SFP if necessary. Try cleaning the connectors. Check for damage from heat or deterioration from age. 25-36 Fabric OS Message Reference Publication Number: 53-1000242-01
