7.5.2.2 (Optional) Associating a Minor Link Event with an Interface

Context
Minor link events include errored symbol events, errored frame events, and errored frame second
events. If the number of code errors, errored frames, or errored frame seconds detected by an
interface on a link in the configured period reaches or exceeds the configured threshold, the link
is unavailable or has low quality. You can associate an EFM crossing event with an interface.
Then the system sets the administrative status of the interface to Down. In this manner, all
services on the interface are interrupted.
Issue 01 (2014-11-30)
EFM is enabled on the interface.
7. Run:
efm error-frame notification enable
The interface is enabled to detect EFM errored frames.
By default, an interface is not enabled to detect EFM errored frames.
Detecting errored frame seconds
1. Run:
system-view
The system view is displayed.
2. Run:
efm enable
EFM is enabled globally.
3. Run:
interface interface-type interface-number
The view of the interface at one end of the link is displayed.
4. Run:
efm error-frame-second period period
The period for detecting EFM errored frame seconds is set.
By default, the period for detecting errored frame seconds on an interface is 60
seconds.
5. Run:
efm error-frame-second threshold threshold
The threshold for detecting EFM errored frame seconds is set.
By default, the threshold for detecting errored frame seconds on an interface is 1.
6. Run:
efm enable
EFM is enabled on the interface.
7. Run:
efm error-frame-second notification enable
The interface is enabled to detect errored frame seconds.
By default, an interface is not enabled to detect errored frame seconds.
