alarm facility fcs-hysteresis
alarm facility fcs-hysteresis
Use the alarm facility fcs-hysteresis global configuration command to set the frame check sequence
(FCS) error hysteresis threshold as a percentage of fluctuation from the FCS bit-error rate. Use the no
form of this command to set the FCS error hysteresis threshold to its default value.
alarm facility fcs-hysteresis percentage
no alarm facility fcs-hysteresis percentage
Syntax Description
Defaults The default threshold-value is 10 percent.
Command Modes Global configuration
Command History
Usage Guidelines Set a hysteresis threshold to cause an alarm to trigger when the FCS bit-error rate fluctuates near the
configured rate.
You set the FCS hysteresis threshold for all ports on the switch. You set the FCS error rate on a per-port
basis by using the fcs-threshold interface configuration command.
If the threshold is not the default, it appears in the output of the show running-config privileged EXEC
command.
Examples This example shows how to set the FCS error hysteresis to 5 percent. The alarm is not triggered unless
the bit error rate is more than 5 percent from the configured FCS bit-error rate.
Switch(config)# alarm facility fcs-hysteresis 5

percentage Hysteresis threshold fluctuation. The range is 1 to 10 percent.
