cvdslCurrStatus
Module: CISCO-IETF-VDSL-LINE-MIB
OID (symbolic): CISCO-IETF-VDSL-LINE-MIB::cvdslCurrStatus
OID (numeric): 1.3.6.1.4.1.9.10.87.1.1.2.1.7
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 no defects on the line
1 lossOfFraming Vtu failure due to not receiving 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.
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 cvdslCurrStatus?
This is a bitmap of the specific defect conditions currently affecting this VDSL line - distinct bits for loss of framing, loss of signal, loss of power, and others - letting a single poll reveal exactly which failure mode(s) are active rather than just a generic 'down' state. It's the object to check immediately when a line drops, since it tells a technician whether to suspect the CPE's power supply (lossOfPower), a physical cable fault (lossOfSignal), or a framing/negotiation issue (lossOfFraming), each pointing to a very different remediation. A line showing only the lossOfPower bit set, with signal and framing bits clear, strongly suggests the customer's modem lost electrical power rather than any problem with the copper line itself.
