in Passive mode. Active devices should not respond to OAM remote
loopback commands and variable requests from a Passive peer.
Passive mode DTE's configured in Passive mode do not initiate the Discovery process.
Passive DTE's react to the initiation of the Discovery process by the
remote DTE. This eliminates the possibility of passive to passive links.
Passive DTE's shall not send Variable Request or Loopback Control
OAMPDUs.
Loopback
Support Controls whether the loopback support is enabled for the switch port.
Link OAM remote loopback 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 Controls whether the Link Monitor support is enabled for the switch
port. On enabling the Link Monitor support, the DTE supports event
notification that permits the inclusion of diagnostic information.
MIB Retrieval
Support Controls whether the MIB Retrieval Support is enabled for the switch
port. On enabling the MIB retrieval support, the DTE supports polling of
various Link OAM based MIB variables' contents.
Loopback
Operation If the Loopback support is enabled, enabling this field will start a
loopback operation for the port.

4.3.13.2 Event Settings
This page allows the user to inspect the current Link OAM Link Event configurations, and
change them as well.
Items Description
Port The switch port number.
Event Name Name of the Link Event which is being configured.
Error
Window Represents the window period in the order of 1 sec for the observation
of various link events.
Error
Threshold Represents the threshold value for the window period for the
appropriate Link event so as to notify the peer of this error.
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
