Usage Guidelines The bit error rate threshold is used by the switch to detect an increased error rate before performance
degradation seriously affects traffic.
Bit errors can occur for the following reasons:
•
•
•
•
•
•
•
A bit error rate threshold is detected when 15 error bursts occur in a 5-minute period. By default, the
switch disables the interface when the threshold is reached. You can issue a shutdown/no shutdown
command sequence to reenable the interface.
Regardless of the setting of the switchport ignore bit-errors command, the switch generates a syslog
Note
message when bit error threshold events are detected.
Examples The following example shows how to prevent the detection of bit error events from disabling the
interface.
