The 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 enter the shutdown/no shutdown command sequence to reenable the interface.
You can configure the switch to not disable an interface when the threshold is crossed.
To disable the bit error threshold for an interface, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# interface fc
slot/port
Step 3
switch(config-if)# switchport ignore
bit-errors
switch(config-if)# no switchport
ignore bit-errors
The switch generates a syslog message when bit error threshold events are detected, even if the interface
Note
is configured not to be disabled by bit-error threshold events.
Configuring Buffer-to-Buffer Credits
To configure BB_credits for a Fibre Channel interface, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# interface fc
slot/port
