DESCRIPTION
This field indicates the current state of the parser.
Forward: The packet is forwarding packets normally.
Loopback: The Switch is in loopback mode.
Discard: The Switch is discarding non-OAMPDUs because it is trying to or has put the
remote device into loopback mode.
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 Switch is in active mode and is trying to see if the remote
device supports OAM.
Passive Wait: The Switch 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 Switch has discovered the remote device but has not accepted or rejected
the connection yet.
• The Switch has discovered the remote device and rejected the connection.
Send Local Remote OK: The Switch 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 Switch and the remote device have accepted the connection. This is
the operating state for OAM links that are fully operational.
