Fw-1163; Fw-1164; Fw-1165 - Brocade Communications Systems SN3000B Reference

Losses of synchronization commonly cause link failures. If you receive concurrent loss of
synchronization errors, troubleshoot the loss of synchronization.
Severity WARNING

FW-1163

Message
<timestamp>, [FW-1163], <sequence-number>,, INFO, <system-name>, <Port Name>,
<Label>, is between high and low boundaries(High=<High value>, Low=<Low value>).
Current value is <Value> <Unit>.
Probable Cause Indicates that the number of link failures that the port experiences has changed from a value
outside of the acceptable range to a value within the acceptable range. Link loss errors occur when
a link experiences a loss of signal and fails. Both physical and hardware problems can cause link
loss errors. Link loss errors frequently occur due to a loss of synchronization. Check for concurrent
loss of synchronization errors and, if applicable, troubleshoot them.
Recommended No action is required. Respond to this message as is appropriate to the particular policy of the
Action end-user installation.
Severity INFO

FW-1164

Message
<timestamp>, [FW-1164], <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 synchronization losses that the port experiences has changed. Loss of
synchronization errors frequently occur due to a faulty small form-factor pluggable (SFP) or cable.
Signal losses often create synchronization losses.
Recommended Check both ends of your cable connection. Verify that the cable and small form-factor pluggables
Action (SFPs) are not faulty.
If you continue to experience synchronization loss errors, troubleshoot your host bus adaptor (HBA)
and contact your switch service provider.
Severity INFO

FW-1165

Message
<timestamp>, [FW-1165], <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 synchronization losses that the port experiences has fallen below the
low boundary. Loss of synchronization errors frequently occur due to a faulty small form-factor
pluggable (SFP) or cable. Signal losses often create synchronization losses. A low number of
synchronization losses means that the switch is functioning normally.
