3.7.1 802.3ah Configuration
To use the OAM functions, the 802.3ah Function setting must be enabled. It is not enabled by default. The 802.3ah mode is used to
configure an OAM pair. In a pair, one unit must be ‘active’, while the other must be ‘passive’. We typically place the remote converter (CPE) in
‘passive’ mode and make the local converter ‘active’. ‘Passive’ is the default setting when 802.3ah function is enabled.
The 802.3ah function supports Event Notification with user-defined Alarm Thresholds for alarm reporting. This allows the service provider
to monitor alarm thresholds to verify the given SLA (Service Level Agreement) of the line. These alarms are reported in the f
orm of “Error
Events” when the errors in a given “Window” size reach a pre-defined threshold. Use the radio button to enable or disable
link events .
Definitions:
* Error Symbol Period (error symbols per second): The number of symbol errors that occurred during a specified period exceeded a threshold.
These errors are coding symbol errors.
* Error Frame (error frames per second): The number of frame errors detected during a specified period exceeded a threshold.
