OAM Configuration

• 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)
Critical events include various failures, such as abnormal voltage fluctuations,
out-of-range temperature detected, fan failure, CRC error in flash memory, insufficient
memory, or other hardware faults.
• Errored Frame – Controls reporting of errored frame link events.
An errored frame is a frame in which one or more bits are errored.
An errored frame link event occurs if the threshold is reached or exceeded within the specified
period.
If reporting is enabled and an errored frame link event occurs, the local OAM entity (this
switch) sends an Event Notification OAMPDU to the remote OAM entity. The Errored Frame
Event TLV includes the number of errored frames detected during the specified period.
• Status – Enables reporting of errored frame link events. (Default: Enabled)
• Window Size – The period of time in which to check the reporting threshold for errored
frame link events. (Range: 10-65535 in units of 10 milliseconds; Default: 10 units of 10
milliseconds, or the equivalent of 1 second)
• Threshold Count – The threshold for errored frame link events.
(Range: 1-65535; Default: 1)
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.
