Basic port parameter configuration
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.
Example
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.
Example
The ERR-DIS entry under the “Link” column indicates the port is down due to link errors.
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 is Idle, 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.
