CHAPTER 4
WEB OPERATION & CONFIGURATION
Loopback Support:
Select the checkbox to enable loopback support on a port. Link OAM remote loopback support can
be used for fault localization and link performance testing. Enabling the loopback support will allow the DTE to
execute the remote loopback command that helps in the fault detection.
Link Monitor Support:
Select the checkbox to enable link monitor support. Once enabled, the DTE supports event
notification that permits the inclusion of diagnostic information.
MIB Retrieval Support:
Select the checkbox to enable MIB retrieval support. Once enabled, the DTE supports polling
of various link OAM based MIB variables’ contents.
Loopback Operation:
If the “Loopback Support” is enabled, selecting the “Loopback Operation” checkbox will start a
loopback operation for the port.
4.3.6.2 Event Settings
Link Event can be configured on a per-port basis. Select the desire port number from the pull-down menu to configure
its Link Event settings.
Event Name:
Ethernet OAM entities monitor link status by exchanging Event Notification OAMPDUs. When one of the
events listed here is detected, an OAM entity sends an Event Notification OAMPDU to its peer OAM entity.
Error Frame Event:
The Errored Frame Event counts the number of errored frames detected during the specified
period. The period is specified by a time interval (Window in order of 1 sec). This event is generated if the errored
frame count is equal to or greater than the specified threshold for that period (Period Threshold). Errored frames
are frames that had transmission errors as detected at the Media Access Control sublayer. Error Window for
'Error Frame Event' must be an integer value between 1-60 and its default value is '1'. Whereas Error Threshold
must be between 0-0xffffffff and its default value is '0'.
Symbol Period Error Event:
The Errored Symbol Period Event counts the number of symbol errors that occurred
during the specified period. The period is specified by the number of symbols that can be received in a time
interval on the underlying physical layer. This event is generated if the symbol error count is equal to or greater
than the specified threshold for that period. Error Window for 'Symbol Period Error Event' must be an integer
value between 1-60 and its default value is '1'. Whereas Error Threshold must be between 0-0xffffffff and its
default value is '0'.
Seconds Summary Event:
The Errored Frame Seconds Summary Event TLV counts the number of errored frame
seconds that occurred during the specified period. The period is specified by a time interval. This event is
generated if the number of errored frame seconds is equal to or greater than the specified threshold for that
period. An errored frame second is a one second interval wherein at least one frame error was detected. Errored
frames are frames that had transmission errors as detected at the Media Access Control sublayer. Error Window
for 'Seconds Summary Event' must be an integer value between 10-900 and its default value is '60'. Whereas
Error Threshold must be between 0-0xffff and its default value is '1'.
Error Window:
Specify the window period in the order of 1 sec for the observation of various link events.
