fcs-threshold
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.
fcs-threshold value
no fcs-threshold value
Syntax Description
Defaults The default rate is 8, which is the bit error rate for Ethernet standard 10
-8
.
Command Modes Interface configuration
Command History
Usage Guidelines The Ethernet standard calls for a maximum bit error rate of 10
-8
. In the IE 3000 switch, the bit error rate
configurable range is from 10
-6
to 10
-11
. The bit error rate input to the switch is a positive integer. To
configure a bit error rate of 10
-9
, enter the value 9 for the exponent.
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
-10
:
Switch(config)# interface fastethernet1/1
Switch(config-if)# fcs-threshold 10
Related Commands
value Value ranges from 6 to 11, representing a bit-error rate from 10
-6
to 10
-11
.
Release Modification
12.2(44)EX This command was introduced.
Command Description
alarm facility fcs-hysteresis Sets the FCS hysteresis threshold for the switch in a percentage of
allowed fluctuation from the FCS bit error rate configured on a port.
show fcs-threshold Displays the FCS error bit rate settings on each interface as positive
exponents.
