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 and no shutdown
command sequence to reenable the interface.
You can configure the switch to not disable an interface when the threshold is crossed. By default, the
threshold disables the interface.
To disable the bit error threshold for an interface, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc1/1
switch(config-if)#
Step 3
switch(config-if)# switchport ignore
bit-errors
switch(config-if)# no switchport ignore
bit-errors
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.
Switch Port Attribute Default Values
You can configure attribute default values for various switch port attributes. These attributes will be
applied globally to all future switch port configurations, even if you do not individually specify them at
that time.
To configure switch port attributes, follow these steps:
