LABEL DESCRIPTION
Discovery This field indicates the state in the OAM discovery process. OAM-enabled devices use this
state
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 and is trying to see if the remote device
supports OAM.
Passive Wait: The port is in passive mode and 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.
