51-1 config ethernet_oam ports
Description
This command is used to configure Ethernet Operations, Administration, and Maintenance (OAM).
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.
