Usage Guidelines

Usage Scenario

After a device is enabled to detect bit errors, errored frames, and errored frame seconds, run the display efm link-event local command to view statistics about local link events.

Prerequisites

EFM OAM has been enabled globally and on an interface, and errored frame detection, and errored frame second detection have been enabled on the interface.

Precautions

After the display efm link-event local command is run, a hyphen (-) is displayed if errored frame detection, and errored frame second detection are not configured in the interface view.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display statistics about local link events on GE 0/1/1.
