Fabric OS Message Reference 311
53-1001767-01
FW-1181
42
Probable Cause Indicates that the number of invalid cyclic redundancy checks (CRCs) that the port experiences has
changed.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation. Frequent fluctuations in CRC errors generally indicate an aging fabric. Check
your small form-factor pluggables (SFPs), cables, and connections for faulty hardware. Verify that
all optical hardware is clean.
Severity INFO
FW-1181
Message
<timestamp>, [FW-1181], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, is below low boundary(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Probable Cause Indicates that the number of invalid cyclic redundancy checks (CRCs) that the port experiences has
fallen below the low boundary.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation. A low number of invalid CRCs means that the switch is functioning normally.
Severity INFO
FW-1182
Message
<timestamp>, [FW-1182], <sequence-number>,, WARNING, <system-name>, <Port Name>,
<Label>, is above high boundary(High=<High value>, Low=<Low value>). Current value
is <Value> <Unit>.
Probable Cause Indicates that the number of invalid cyclic redundancy checks (CRCs) that the port experiences has
risen above the high boundary.
Recommended
Action
This error generally indicates an deteriorating fabric hardware. Check your small form-factor
pluggables (SFPs), cables, and connections for faulty hardware. Verify that all optical hardware is
clean.
Severity WARNING
FW-1183
Message
<timestamp>, [FW-1183], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, is between high and low boundaries(High=<High value>, Low=<Low value>).
Current value is <Value> <Unit>.
Probable Cause Indicates that the number of invalid cyclic redundancy checks (CRCs) that the port experiences has
changed from a value outside of the acceptable range to a value within the acceptable range.
