event-notification
Syntax event-notification
[no] event-notification
Context config>port>ethernet>efm-oam>link-monitoring>errored-symbols
Description This command allows the symbol error event threshold crossing actions to transmit the Event Notification
OAMPDU with the specific Link Event TLV information. The Event Notification OAM PDU will only be
generated on the initial sf-threshold is reached. No subsequent notification will be sent until the event that
triggered the notification clears, through manual intervention or a window where the configured sd-thresh-
old is not reached. The burst parameter under the local-sf-action will determine the number of Event Notifi-
cation OAMPDUs to generate when the event occurs. The reception of the event notification will be
processed regardless of this parameter.
The no version of this command will disable the transmission of the Event Notification OAMPDU for this
event type.

event-notification
sd-threshold
Syntax sd-threshold errored-symbols
[no] sd-threshold
Context config>port>ethernet>efm-oam>link-monitoring>errored-symbols
Description This option is used to define the number of errored frames within the configured window which indicates the
port has gone beyond an acceptable error rate and should be considered degraded. This is a first level warn-
ing that a port may be suspect. An event is raised when the error count is equal to or greater than this value.
This is an information log event message only and will be recorded in the Port event index but has no port
level actions. This value must be lower than or equal to the sf-threshold value. Specific to symbol errors,
this value must be configured with the value that indicates anything less is acceptable and the port can be
returned to service. If this value is not configured then manual operation is required to return the port to ser-
vice.
The no value of this option means there is there is no automatic return to service.
Default [no] sd-threshold
Parameters errored-symbols — The number of errored symbols which indicates the port has become degraded.
