Low=<Low value>). Current value is <Value> <Unit>.
Message Type
LOG
Severity
INFO
Probable Cause
Indicates that the number of invalid words that the port experiences has changed from a value outside of
the acceptable range to a value within the acceptable range. Invalid words usually indicate a hardware
problem with a small form-factor pluggable (SFP) or cable.

<Port Name> <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. A low number of invalid CRCs means that the switch is functioning
normally.
