DESCRIPTION
This field indicates the state in the OAM discovery process. OAM-enabled devices use
this process to detect each other and to exchange information about their OAM
configuration and capabilities. OAM discovery is a handshake protocol.
Fault: One of the devices is transmitting OAM PDUs with link fault information, or
the interface is not operational.
Active Send Local: The port is in active mode so it is trying to see if the remote
device supports OAM.
Passive Wait: The port is in passive mode so it is waiting for the remote device to
begin OAM discovery.
Send Local Remote: This state occurs in the following circumstances.
• The port has discovered the remote device but has not accepted or rejected the
connection yet.
• The port has discovered the remote device and rejected the connection.
Send Local Remote OK: The port has discovered the remote device and has
accepted the connection. In addition, the remote device has not accepted or rejected
the connection yet, or the remote device has rejected the connected.
Send Any: The port and the remote device have accepted the connection. This is the
operating state for OAM links that are fully operational.
This is the subscriber Ethernet device's MAC address.
This is the organizationally unique identifier (OUI) assigned by the IEEE to the
vendor of the remote device. It is contained in the first 24 bits of the MAC address.
This shows whether or not remote device has OAM functionality enabled for this port.
This shows whether or not the remote device has OAM remote loopback functionality
enabled for this port.
This is the largest OAM Protocol Data Unit the remote device can use for an OAM
remote loopback test (in bytes).
This field displays the current version of local state and configuration. This two-octet
value starts at zero and increments every time the local state or configuration
changes.
