alarm facility fcs-hysteresis Chapter 2 IE 3000 Switch Cisco IOS Commands 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 percentage Hysteresis threshold fluctuation. The range is 1 to 10 percent. Defaults The default threshold-value is 10 percent. Command Modes Global configuration Command History Release 12.2(44)EX Modification This command was introduced. 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 Related Commands Command fcs-threshold show running-config Description Sets an FCS error rate for an interface. Displays the running configuration on the switch, including FCS hysteresis threshold if it is not set at the default. Cisco IE 3000 Switch Command Reference 2-6 OL-13019-01
