OAM Parameter

In this interface, you can configure and query parameters related to the Ethernet port OAM.

Navigation Path

For RTN NEs, in the NE Explorer, select an NE and choose Configuration > Ethernet OAM Management > Ethernet Port OAM Management. Then, click the OAM Parameter tab.

Buttons

Button	Description
OAM	Enables or disables the remote loopback. You can enable or disable the remote loopback only when the transmit end works in the active mode, and the loopback end enables the OAM and supports the remote loopback.

Parameters

**Table 1** Descriptions of the parameters for OAM
Field	Value	Description
Port	slot number-board name-port number (port name)	Sets the function port for the OAM.
Enable OAM Protocol	Disabled, Enabled	Enables or disables the OAM protocol.
OAM Working Mode	Active, Passive	Set the OAM working mode. Active indicates that the port works in the active mode, and can start the OAM packets. Passive indicates that the port works in the passive mode, and cannot start the OAM packets, but can respond to the packets started by the opposite.
Link Event Notification	Disabled, Enabled	Enables or disables the link event notification. If the performance events cross the threshold at the local port, the local port notifies the opposite port by using the link events.
Remote Side Loopback Response	Disabled, Enabled	Enables or disables the remote side loopback response. If the port does not support the remote loopback, the port does not respond to the loopback request of the opposite port, no matter what status the OAM port is in.
Loopback Status	Initiate Loopback at Local, Respond Loopback of Remote, Non-Loopback	Displays the local loopback status.
OAM Discovery Status	FAULT, ACTIVE_SEND_LOCAL, PASSIVE_WAIT, SEND_LOCAL_REMOTE, SEND_LOCAL_REMOTE_OK, SEND_ANY	Displays the local OAM discovery status.
Port Transmit Status	FWD, DISCARD	Displays the port transmit status. FWD indicates that port transmits the non-OAM packets. DISCARD indicates that the port discards the non-OAM packets.
Port Receive Status	FWD, LB, DISCARD	Displays the port receive status. FWD indicates that port forwards the non-OAM packets to the upper layer. LB indicates that the port loops back the non-OAM packets. DISCARD indicates that the port discards the non-OAM packets.
Protocol Packet Transmission Period (100 ms)	Example: 10	Sets the OAM packet transmission period for the local NE. After this parameter is set, the local NE sends OAM packets to the peer NE according to the specified period.
Multiple of Protocol Packet Timeout	Example: 12	Indicates the multiple of the OAM packet receiving timeout period for the local NE. This parameter works with the Protocol Packet Transmission Period parameter to define the timeout period as follows: Timeout period = Protocol packet transmission period x Multiple of protocol packet timeout The local NE reports an alarm if it does not receive an OAM packet from the peer NE within the timeout period.
