OAM Control

101

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

Returned only by OAM entities in OAM Mode passive. Reflects the state in which

the OAM entity is waiting to see if the peer device is OA capable.

Active Send Local

Used by active mode devices. This value reflects the OAM entity actively

trying to discover whether the peer has OAM capability.

Send Local And Remote

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

Message displayed when the local OAM entity rejects the peer OAM

entity.

Send Local and remote OK

OAM peering is allowed by the local device.

OAM peering Remotely Rejected

The remote OAM entity rejects the peering.

Operational

Local and remote OAM entities have accepted the peering and OAM is up and

running.

Non OperHalf Duplex

This message is displayed when OAM is enabled on a half duplex link, as

it is not intended to function on a half duplex link.

9.1.2 OAM Max PDU Size

The OAM maximum PDU size that the 9145E supports. If the OAM maximum PDU size of the
9145E differs from that of its peers, the smaller of the two maximum OAMPDU sizes will be used
between the peers.

9.1.3 OAM Revision

The revision number increments when there is a change in the OAM configuration of the 9145E.
The change in revision number triggers the peer to re-evaluate whether OAM peering is allowed.

9.1.4 OAM Functions

The following functions are communicated to the peer and supported in the 9145E OAM
application.

1. Unidirectional The 9145E supports the transmission of OAM PDU on links that are operating in

unidirectional mode.

2. LoopBack The 9145E can initiate and respond to loopback commands.

3. Link Events The 9145E can send and receive event notification OAMPDU.

9.1.5 OAM Loopback Status

This setting returns the status and states. Four states are available: no loopback, initiating
loopback, remote loopback, and terminating loopback.

9.1.6 OAM Remote Fault

This setting indicates whether a remote fault OAM PDU was sent by the peer to the 9145E.
