Configuring Switch Alarms
Setting the FCS Error Hysteresis Threshold
The hysteresis setting prevents the toggle of an alarm when the actual bit error rate fluctuates near the
configured rate. Use the alarm facility fcs-hysteresis global configuration command to set the FCS
error hysteresis threshold.
Note The FCS hysteresis threshold is applied to all ports of a switch.
BEFORE YOU BEGIN
Review the “FCS Error Hysteresis Threshold” section on page 5-2.
DETAILED STEPS
Use the no alarm facility fcs-hysteresis command to set the FCS error hysteresis threshold to its default
value.
Note The show running config command displays any FCS error hysteresis that is not the default value.
EXAMPLE
This example shows how to set the FCS error hysteresis at 5 percent:
Switch(config)# alarm facility fcs-hysteresis 5

You can use the alarm profile global configuration command to create an alarm profile or to modify an
existing profile. When you create a new alarm profile, none of the alarms are enabled.
