config ethernet_oam ports
Description
This command is used to configure Ethernet OAM. The parameter to configure port Ethernet OAM mode operates
in active or passive mode. The following two actions are allowed by ports in active mode, but disallowed by ports in
passive mode: Initiate OAM discovery and start or stop remote loopback. Note that when a port is OAM-enabled,
changing the OAM mode will cause the OAM discovery to be re-started.
The command used to enable or disable port’s Ethernet OAM function. The parameter enabling a port’s OAM will
cause the port to start OAM discovery. If a port’s is active, it initiates the discovery. Otherwise it reacts to the
discovery received from peer. Disabling a port’s OAM will cause the port to send out a dying gasp event to peers
and then disconnect the established OAM link.
The link monitoring parameter is used to configure port Ethernet OAM link monitoring error symbols. The link
monitoring function provides a mechanism to detect and indicate link faults under a variety of conditions. OAM
monitors the statistics on the number of frame errors as well as the number of coding symbol errors. When the
number of symbol errors is equal to or greater than the specified threshold in a period and the event notification
state is enabled, it generates an error symbol period event to notify the remote OAM peer. The Ethernet OAM link
monitoring error frames parameter provides a mechanism to detect and indicate link faults under a variety of
conditions. OAM monitors the counter on the number of frame errors as well as the number of coding symbol
errors. When the number of frame errors is equal to or greater than the specified threshold in a period and the
event notification state is enabled, it generates an error frame event to notify the remote OAM peer.
The link event parameter configures the capability of the Ethernet OAM critical link event. If the capability for an
event is disabled, the port will never send out the corresponding critical link event. The command is used to
configure the client to process or to ignore the received Ethernet OAM remote loopback command. In remote
loopback mode, all user traffic will not be processed. Ignoring the received remote loopback command will prevent
the port from entering remote loopback mode.
