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 No action is required. Respond to this message as is appropriate to the particular policy of the
Action 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.
Severity INFO

FW-1522

Message
<timestamp>, [FW-1522], <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 (CRCs) that the port experiences has
dropped below upper threshold boundary to a value within the acceptable range.
Recommended No action is required. Respond to this message as is appropriate to the particular policy of the
Action 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.
Severity INFO

FW-1523

Message
<timestamp>, [FW-1523], <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 percentage of incoming traffic that the port experiences has changed and
crossed lower threshold boundary to a value within the acceptable range.
Recommended No action is required. Respond to this message as is appropriate to the particular policy of the
Action end-user installation.
