FW-1180

Message
<timestamp>, [FW-1180], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, value has changed(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
changed.
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 (SFPs), cables, and connections for faulty hardware. Verify that
all optical hardware is clean.
Severity INFO

FW-1181

Message
<timestamp>, [FW-1181], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, is below low boundary(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
fallen below the low boundary.
Recommended No action is required. Respond to this message as is appropriate to the particular policy of the
Action end-user installation. A low number of invalid CRCs means that the switch is functioning normally.
Severity INFO

FW-1182

Message
<timestamp>, [FW-1182], <sequence-number>,, WARNING, <system-name>, <Port Name>,
<Label>, is above high boundary(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
risen above the high boundary.
Recommended This error generally indicates an deteriorating fabric hardware. Check your small form-factor
Action pluggables (SFPs), cables, and connections for faulty hardware. Verify that all optical hardware is
clean.
