CHAPTER 3
WEB OPERATION & CONFIGURATION
Unidirectional Operation Support:
This feature is not available to be configured by the user. The status of this
configuration is retrieved from the PHY.
Remote Loopback Support:
If status is enabled, the device is capable of OAM remote loopback mode.
Link Monitoring Support:
If status is enabled, the device supports interpreting Link Events.
MIB Retrieval Support:
If status is enabled, the device supports sending Variable Response OAMPDUs.
MTU Size:
It represents the largest OAMPDU, in octets, supported by the device. This value is compared to the
remotes Maximum PDU Size and the smaller of the two is used.
Multiplexer State:
When in forwarding state, the device is forwarding non-OAMPDUs to the lower sub-layer. In case
of discarding, the device discards all the non-OAMPDU's.
Parser State:
When in forwarding state, the device is forwarding non-OAMPDUs to higher sub-layer. When in
loopback, the device is looping back non-OAMPDUs to the lower sub-layer. When in discarding state, the device is
discarding non-OAMPDUs.
Organizational Unique Identification:
24-bit Organizationally Unique Identifier of the vendor.
PDU Revision:
It indicates the current revision of the Information TLV. The value of this field shall start at zero and be
incremented each time something in the Information TLV changes. Upon reception of an Information TLV from a peer,
an OAM client may use this field to decide if it needs to be processed (an Information TLV that is identical to the
previous Information TLV doesn't need to be parsed as nothing in it has changed).
3.6.5 Event Status
Local & Remote Frame Error Status
Sequence Number:
This two-octet field indicates the total number of events occurred at the remote end.
Frame Error Event Timestamp:
This two-octet field indicates the time reference when the event was generated, in
terms of 100 ms intervals.
Frame error event window:
This two-octet field indicates the duration of the period in terms of 100 ms intervals. 1)
The default value is one second. 2) The lower bound is one second. 3) The upper bound is one minute.
