Parameters
These parameters are displayed:
•
Port – Port identifier. (Range: 1-12)
•
Admin Status – Enables or disables OAM functions. (Default: Disabled)
•
Operation State – Shows the operational state between the local and remote OAM devices.
This value is always “disabled” if OAM is disabled on the local interface.
•
Mode – Sets the OAM operation mode. (Default: Active)
•
Active – All OAM functions are enabled.
•
Passive – All OAM functions are enabled, except for OAM discovery, sending variable
request OAMPDUs, and sending loopback control OAMPDUs.
•
Critical Link Event – Controls reporting of critical link events to its OAM peer.
•
Dying Gasp – If an unrecoverable condition occurs, the local OAM entity (i.e., this switch)
indicates this by immediately sending a trap message. (Default: Enabled)
Dying gasp events are caused by an unrecoverable failure, such as a power failure or
device reset.
NOTE
When system power fails, the switch will always send a dying gasp trap message prior to
power down.
•
Critical Event – If a critical event occurs, the local OAM entity indicates this to its peer by
setting the appropriate flag in the next OAMPDU to be sent and stores this information in
its OAM event log. (Default: Enabled)
TABLE 180
OAM Operation State
State
Description
Disabled
OAM is disabled on this interface via the OAM Admin Status.
Link Fault
The link has detected a fault or the interface is not operational.
Passive Wait
This value is returned only by OAM entities in passive mode and indicates
the OAM entity is waiting to see if the peer device is OAM capable.
Active Send Local
This value is used by active mode devices and indicates the OAM entity is
actively trying to discover whether the peer has OAM capability but has
not yet made that determination.
Send Local And Remote
The local OAM entity has discovered the peer but has not yet accepted or
rejected the configuration of the peer.
Send Local And Remote OK
OAM peering is allowed by the local device.
OAM Peering Locally Rejected
The local OAM entity rejects the peering.
OAM Peering Remotely Rejected
The remote OAM entity rejects the peering.
Operational
When the local OAM entity learns that both it and the remote OAM entity
have accepted the peering, the state moves to this state.
Non Oper Half Duplex
This state is returned whenever Ethernet OAM is enabled but the
interface is in half-duplex operation.
