FW-3101
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 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 the switch is functioning normally.
FW-3102
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 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 small form-factor pluggable (SFP)
transceivers, cables, and connections for faulty hardware. Verify that all optical hardware is clean.
FW-3103
Message
<Label>, is between high and low boundaries(High=<High value>, Low=<Low value>).
Current value is <Value> <Unit>.
Message Type
LOG
Severity
INFO
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.
Recommended
Action
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 the small form-factor pluggable
(SFP) transceivers, cables, and connections for faulty hardware. Verify that all optical hardware is clean.
