The switch generates a syslog message when bit error threshold events are detected, even if the interface
is configured not to be disabled by bit-error threshold events.
Note
To disable the bit error threshold for an interface, perform this task:
Procedure
Purpose
Command or Action
Enters configuration mode.
switch#
configuration terminal
Step 1
Selects a Fibre Channel interface and enters interface
configuration mode.
switch(config)#
interface fc slot
/
port
Step 2
If this is a QSFP+ GEM, the
slot
/
port
syntax
is
slot
/
QSFP-module
/
port
.
Note
Prevents the detection of bit error threshold events
from disabling the interface.
switch(config-if)#
switchport ignore
bit-errors
Step 3
Prevents the detection of bit error threshold events
from enabling the interface.
switch(config-if)#
no switchport
ignore bit-errors
Step 4
Configuring Buffer-to-Buffer Credits
Procedure
Purpose
Command or Action
Enters global configuration mode.
switch#
configure terminal
Step 1
Selects a Fibre Channel interface and enters interface
configuration mode.
switch(config)#
interface fc
slot
/
port
Step 2
If this is a QSFP+ GEM, the
slot
/
port
syntax is
slot
/
QSFP-module
/
port
.
Note
Applies the default operational value to the selected interface.
The operational value depends on the port mode.
switch(config-if)#
switchport
fcrxbbcredit default
Step 3
The default values are assigned based on the port capabilities.
Assigns a buffer-to-buffer credit number to the selected interface
and optionally specifies if the port is operating in E, F, or TE
mode.
switch(config-if)#
switchport
fcrxbbcredit number mode
{
E
|
F
|
TE
}
Step 4
If you specify
E
,
F
, or
TE
for the
mode
, the
buffer-to-buffer credit value is applicable only when
the port is set to that particular mode.
