9.1 OAM Control
The OAM Control screen (Figure 9-2) is split into two sections. The top of the screen shows status
information. The list below shows the standard status information and the corresponding MIB objects.
User interface MIB Object
•OAM Operational Status dot3OamOperStatus (dot3oam.my)
•OAM MAX PDU Size dot3OamMaxOamPduSize (dot3oam.my)
•OAM Revision dot3OamConfigRevision (dot3oam.my)
•OAM Functions Supported dot3OamFunctionsSupported (dot3oam.my)
•OAM Loopback Status Dot3OamLoopbackStatus (dot3oam.my)
•OAM Remote Link Fault
OAM Operational Status -
At initialization and failure conditions, two OAM entities on the same full-duplex Ethernet link begin a
discovery phase to determine what OAM capabilities may be used on that link. The following is the list
of possible values:
Disabled: - This value will return “disabled” if OAM is disabled on this interface via the OAM Admin
State.
Link Fault: - If the link has detected a fault and is transmitting OAMPDUs with a link fault indication,
the value is link Fault. This value will also be returned if the interface is not operational.
Passive Wait - The passive Wait state is returned only by OAM entities in OAM Mode passive and
reflects the state in which the OAM entity is waiting to see if the peer device is OA capable.
Active Send Local - This value is used by active mode devices and reflects the OAM entity actively
trying to discover whether the peer has OAM capability but has not yet made that determination.
Send Local And Remote - Reflects that the local OA entity has discovered the peer but has not yet
accepted or rejected the configuration of the peer. The local device can, for whatever reason, decide
that the peer device is unacceptable and decline OAM peering.
Peering Locally rejected - This message appears when the local OAM entity rejects the peer OAM
entity.
Send Local and remote OK - This state shows that the OAM peering is allowed by the local device.
OAM peering Remotely Rejected - This state show that the remote OAM entity rejects the peering.
Operational - Indicate that local and remote OAM entities have accepted the peeing. And OAM is up
and running.
Non OperHalf Duplex - This message is indicated when OAM is enable on a half duplex link as it is
not intended to function on half duplex link.
OAM Max PDU - Is the OAM maximum PDU size that the 9145E support. If the OAM maximum PDU
size is different between the 9145E and its peers, the smaller of the two maximum OAMPDU sizes will
be used between the peers.
OAM Revision -
The revision number increments every time there is a change in the OAM configuration of the 9145E.
The change in revision number will trigger the peer to re-evaluate whether OAM peering is allowed.
