Discovery state 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 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.
Remote Client
MAC Address This field displays the MAC address of the IEEE 802.3ah-enabled remote Ethernet device
that is connected to the Switch.
Vendor(oui) This field displays the Organizationally Unique Identifiers (OUI) representing the vendor of
the IEEE 802.3ah-enabled remote Ethernet device that is connected to the Switch.
Statistics
This section displays the number of OAM packets transferred on the port of the Switch.
Information OAMPDU
Tx
This field displays the number of OAM PDUs sent on the port.
Information OAMPDU
Rx
This field displays the number of OAM PDUs received on the port.
Event Notification
OAMPDU Tx
This field displays the number of unique or duplicate OAM event notification PDUs sent on
the port.
Event Notification
OAMPDU Rx
This field displays the number of unique or duplicate OAM event notification PDUs received
on the port.
Loopback Control
OAMPDU Tx
This field displays the number of loopback control OAM PDUs sent on the port.
Loopback Control
OAMPDU Rx
This field displays the number of loopback control OAM PDUs received on the port.
Variable Request
OAMPDU Tx
This field displays the number of OAM PDUs sent to request MIB objects on the remote
device.
Variable Request
OAMPDU Rx
This field displays the number of OAM PDUs received requesting MIB objects on the Switch.
Variable Response
OAMPDU Tx
This field displays the number of OAM PDUs sent by the Switch in response to requests.
Variable Response
OAMPDU Rx
This field displays the number of OAM PDUs sent by the remote device in response to
requests.
