Link OAM Port Settings
This page lets you view and edit the current Link OAM port configurations from the

Port
The S4224 port number. Click on a specific port number in the table to display that port’s ‘Detailed
Link OAM Status’. The
*
in the Port column acts as a ‘wild card’ character which causes the
selections in this row to be applied to all other rows in the table for which this selection is valid. See
the
Monitor
>
Link OAM
>
Port Statistics
section for more information.
OAM Enabled
Controls whether Link OAM is enabled on this S4224 port. Enabling Link OAM provides the network
operator the ability to monitor the health of the network and quickly determine the location of failing
links or fault conditions.
OAM Mode
Configures the OAM Mode as
Active
or
Passive
. The default mode is
Passive
.
Active:
DTEs configured in Active mode initiate the exchange of Information OAMPDUs as defined
by the Discovery process. Once the Discovery process completes, Active DTEs are permitted to send
any OAMPDU while connected to a remote OAM peer entity in Active mode. Active DTEs operate in
a limited respect if the remote OAM entity is operating in Passive mode. Active devices should not
respond to OAM remote loopback commands and variable requests from a Passive peer.
Passive:
DTEs configured in Passive mode do not initiate the Discovery process. Passive DTEs
react to the initiation of the Discovery process by the remote DTE. This eliminates the possibility of
passive to passive links. Passive DTE' will not send Variable Request or Loopback Control
OAMPDUs.
Loopback Support
Controls whether the loopback support is enabled for the S4224 port. Link OAM remote loopback can
be used for fault localization and link performance testing. Enabling the loopback support allows 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 S4224 port. On enabling the Link
Monitor support, the DTE supports event notification that permits the inclusion of diagnostic
information.
