vdslPhysCurrStatus
Module: VDSL-LINE-MIB
OID (symbolic): VDSL-LINE-MIB::vdslPhysCurrStatus
OID (numeric): 1.3.6.1.2.1.10.97.1.1.2.1.7
Node type: OBJECT-TYPE
Type: Bits
Access: read-only
Description: Indicates current state of the Vtu line. This is a bit-map of possible conditions. The various bit positions are:
0 noDefect There are no defects on the line.
1 lossOfFraming Vtu failure due to not receiving a valid frame.
2 lossOfSignal Vtu failure due to not receiving signal.
3 lossOfPower Vtu failure due to loss of power.
4 lossOfSignalQuality Loss of Signal Quality is declared when the Noise Margin falls below the Minimum Noise Margin, or the bit-error-rate exceeds 10^-7.
5 lossOfLink Vtu failure due to inability to link with peer Vtu. Set whenever the transceiver is in the 'Warm Start' state.
6 dataInitFailure Vtu failure during initialization due to bit errors corrupting startup exchange data.
7 configInitFailure Vtu failure during initialization due to peer Vtu not able to support requested configuration.
8 protocolInitFailure Vtu failure during initialization due to incompatible protocol used by the peer Vtu.
9 noPeerVtuPresent Vtu failure during initialization due to no activation sequence detected from peer Vtu.
This is intended to supplement ifOperStatus.
What is vdslPhysCurrStatus?
Encodes the VTU's current defect state as a bitmap, with individual bits flagging conditions such as loss of framing, loss of signal, loss of power, poor signal quality, loss of link, or failures during data/config/protocol initialization or peer detection. An admin polls this alongside ifOperStatus to pinpoint why a VDSL line is down or degraded, for example distinguishing a dead peer (noPeerVtuPresent) from a configuration mismatch (configInitFailure).
