Port8/5 is configured for link-error-disable
threshold:4, sampling_period:10, waiting_period:2
Port8/9 is configured for link-error-disable
threshold:2, sampling_period:20, waiting_period:0
For FastIron X Series devices, the output of the command shows the following.
device# show link-error-disable all

Displaying ports configured with port flap dampening defines the port flap dampening statistics
displayed by the show link-error-disable all command.
Output of show link-error-disable TABLE 9
Column Description
Port # The port number.
Threshold The number of times the port link state will go from up to down and down to up before the wait
period is activated.
Sampling-Time The number of seconds during which the specified toggle threshold can occur before the wait
period is activated.
Shutoff-Time The number of seconds the port will remain disabled (down) before it becomes enabled. A zero (0)
indicates that the port will stay down until an administrative override occurs.
State The port state can be one of the following:
• Idle - The link is normal and no link state toggles have been detected or sampled.
• Down - The port is disabled because the number of sampled errors exceeded the configured
threshold.
• Err - The port sampled one or more errors.
Counter • If the port state isIdle , this field displays N/A .
• If the port state is Down , this field shows the remaining value of the shutoff timer.
• If the port state is Err , this field shows the number of errors sampled.
Syntax: show link-error-disable [ all ]
Also, in FastIron X Series devices, the show interface command indicates if the port flap dampening
feature is enabled on the port.
