FW-1519
Message <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
Action
No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation.
Severity INFO
FW-1520
Message <timestamp>, [FW-1520], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, has dropped below upper 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 dropped
below upper 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
Action
No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation.
Severity INFO
FW-1521
Message <timestamp>, [FW-1521], <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 cyclic redundancy checks (CRC) that the port experiences
crossed lower threshold boundary to a value within the acceptable range.
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 (SFP), cables, and connections for faulty hardware. Verify that all
optical hardware is clean.
