Command History
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:
• Faulty or bad cable
• Faulty or bad SFP
• SFP is specified to operate at 1 Gbps but is used at 2 Gbps
• Short haul cable is used for long haul or long haul cable is used for short haul
• Momentary sync loss
• Loose cable connection at one or both ends
• Improper SFP connection at one or both ends
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 enter 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
message when bit error threshold events are detected.
