The user can configure each port's Ethernet OAM mode to operate in the active or passive mode. The following two actions are allowed, per port, in the active mode, but not allowed, per port, in the passive mode: • Initiate OAM discovery. • Start or stop remote loopback. NOTE: When a port is OAM-enabled, changing the OAM mode will cause the OAM discovery to restart. This command is also used to enable or disable a port's Ethernet OAM function. Enabling a port's OAM will cause the port, if active, to start the OAM discovery or it will react to a discovery packet received from the 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 a port's 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 will monitor 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 will generate 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. 509
