FW-1217
Message <Label>, is below low boundary(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Message Type LOG
Severity INFO
Probable Cause Indicates that the number of Arbitrated Loop Physical Address (ALPA) 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, because only large numbers of messages indicate a problem in this area.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the end-user
installation. A low level of invalid CRC errors means that the switch is functioning normally.
FW-1218
Message <Label>, is above high boundary(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Message Type LOG
Severity WARNING
Probable Cause Indicates that the number of cyclic redundancy check (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 set your high boundaries to five- or six-digit figures, because only large
numbers of messages indicate a problem in this area.
Recommended
Action
You should configure a five- or six-figure high boundary for this area. Only five-figure (or higher) values
for CRC errors indicate problems. Check for a faulty cable or deteriorated small form-factor pluggable
(SFP). Replace the cable or the SFP if necessary. Clean the connectors. Check for damage from heat or
deterioration from age.
