The threshold for detecting errored frame seconds on the interface is set.
By default, the threshold for detecting errored frame seconds on an interface is 1.
Step 5 Run:
efm error-frame-second notification enable
The interface is enabled to detect errored frame seconds.
By default, an interface cannot detect errored frame seconds.

4.4.5 (Optional) Associating a Threshold Crossing Event with an
Interface
After a threshold crossing event is associated with an interface, the system sets the administrative
state of the interface to Down. In this manner, all services on the interface are interrupted.
Context
When an interface on a link is enabled to detect errored frames, errored codes, or errored frame
seconds, the link is considered unavailable, if the number of errored frames, errored codes, or
errored frame seconds detected by the interface reaches or exceeds the threshold within a set
period. The errored frame event, errored code event, and errored frame seconds summary event
are called threshold crossing events. In this case, you can associate a threshold crossing event
with the interface so that the system sets the administrative state of the interface to Down. As a
result, the link actually goes Down and all services on the interface are interrupted.
Do as follows on the device at one end or devices at both ends of a link:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The view of an interface at one end of the link is displayed.
Step 3 Run:
efm threshold-event trigger error-down
A threshold crossing event is associated with the interface.
By default, no threshold crossing event is associated with interfaces.
----End
Follow-up Procedure
After a threshold crossing event is associated with an interface, you can configure the interface
to go administratively Up by using either of the following methods:
