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.
device# show interface ethernet 15
GigabitEthernet15 is up, line protocol is up
Link Error Dampening is Enabled
Port up for 6 seconds
Hardware is GigabitEthernet, address is 0000.0000.010e (bia 0000.0000.010e)
Configured speed auto, actual 1Gbit, configured duplex fdx, actual fdx
Configured mdi mode AUTO, actual MDIX
device# show interface ethernet 17
GigabitEthernet17 is ERR-DISABLED, line protocol is down
Link Error Dampening is Enabled
Port down for 40 seconds
Hardware is GigabitEthernet, address is 0000.0000.010e (bia 0000.0000.010e)
Configured speed auto, actual unknown, configured duplex fdx, actual unknown
The line "Link Error Dampening" displays "Enabled" if port flap dampening is enabled on the port or
"Disabled" if the feature is disabled on the port. The feature is enabled on the ports in the two examples
above. Also, the characters "ERR-DISABLED" is displayed for the "GbpsEthernet" line if the port is
disabled because of link errors.
Syntax: show interface ethernet port-number
In addition to the show commands above, the output of the show interface brief command for FastIron
X Series indicates if a port is down due to link errors.

The ERR-DIS entry under the "Link" column indicates the port is down due to link errors.

Output of show link-error-disable
Description
The port number.
The number of times the port link state will go from up to down and down to up before the wait
period is activated.
period is activated.
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.
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.
• 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.
