Probable Cause Indicates that the number of protocol errors that the port experiences has changed and dropped
below upper threshold boundary to a value within the acceptable range. Occasional protocol errors
occur due to software glitches. Persistent protocol errors occur due to hardware problems.
Recommended No action is required. Respond to this message as is appropriate to the particular policy of the
Action end-user installation.

<timestamp>, [FW-1519], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, has crossed lower threshold boundary to in between(High=<High value>,
Low=<Low value>). Current value is <Value> <Unit>.
Probable Cause Indicates that the number of invalid words that the port experiences has changed and crossed
lower threshold boundary to a value within the acceptable range. Invalid words usually indicate a
hardware problem with a small form-factor pluggable (SFP) or cable.
Recommended No action is required. Respond to this message as is appropriate to the particular policy of the
Action end-user installation.

Probable Cause Indicates that the number of invalid cyclic redundancy checks (CRCs) that the port experiences
crossed lower threshold boundary to a value within the acceptable range.
