Fcs-Threshold - Cisco IE-3000-8TC Command Reference Manual

Chapter 2 IE 3000 Switch Cisco IOS Commands

fcs-threshold

Use the fcs-threshold interface configuration command to set the frame check sequence (FCS) bit-error
rate. Use the no form of the command to return to the default setting.
Syntax Description
value
Defaults The default rate is 8, which is the bit error rate for Ethernet standard 10
Command Modes Interface configuration
Command History Release
12.2(44)EX
Usage Guidelines The Ethernet standard calls for a maximum bit error rate of 10
configurable range is from 10
configure a bit error rate of 10
You can set an FCS error hysteresis threshold on the switch to prevent the toggle of the alarm when the
actual bit error rate fluctuates near the configured bit error rate by using the alarm facility fcs hysteresis
global configuration command.
Examples
This example shows how to set the FCS bit error rate for a port to 10
Switch(config)# interface fastethernet1/1
Switch(config-if)# fcs-threshold 10

Description
Sets the FCS hysteresis threshold for the switch in a percentage of
allowed fluctuation from the FCS bit error rate configured on a port.
Displays the FCS error bit rate settings on each interface as positive
exponents.
