CISCO-IETF-VDSL-LINE-MIB: View SNMP OID List / Download MIB

The MIB module defining objects for the management of a pair of VDSL modems at each end of the VDSL line. Each VDSL line has an entry in an ifTable. An agent may reside at either end of the VDSL line however the MIB is designed to require no management communication between them beyond that inherent in the low-level VDSL line protocol. The agent may monitor and control this protocol for its needs. VDSL lines may support optional Fast or Interleaved channels. If these are supported, additional entries corresponding to the supported channels must be created in the ifTable. Thus a VDSL line that supports both channels will have three entries in the ifTable, one for each physical, fast, and interleaved, whose ifType values are equal to vdsl(97), fast(125), and interleaved(124), respectively. The ifStackTable is used to represent the relationship between the entries. Naming Conventions: Vtuc -- (VTUC) modem at near (Central) end of line Vtur -- (VTUR) modem at Remote end of line Vtu -- One of either Vtuc or Vtur Curr -- Current Prev -- Previous Atn -- Attenuation ES -- Errored Second. LCS -- Line Code Specific Lof -- Loss of Frame Lol -- Loss of Link Los -- Loss of Signal Lpr -- Loss of Power xyzs -- interval of Seconds in which xyz occurs (e.g., xyz=Lof, Los, Lpr) Max -- Maximum Mgn -- Margin Min -- Minimum Psd -- Power Spectral Density Snr -- Signal to Noise Ratio Tx -- Transmit Blks -- Blocks, a data unit, see cvdslVtuXChanCrcBlockLength

Vtu initialization failed. See cvdslCurrStatus for potential reasons.

This table includes common attributes describing both ends of the line. It is required for all VDSL physical interfaces. VDSL physical interfaces are those ifEntries where ifType is equal to vdsl(97).

An entry in the cvdslLineTable.

Specifies the VDSL coding type used on this line.

Defines the type of VDSL physical line entity that exists, by defining whether and how the line is channelized. If the line is channelized, the value will be other than noChannel(1). This object defines which channel type(s) are supported. In the case that the line is channelized, the manager can use the ifStackTable to determine the ifIndex for the associated channel(s). Enumeration: 'fastOnly': 2, 'both': 5, 'noChannel': 1, 'slowOnly': 3, 'either': 4.

The value of this object identifies the rows in the VDSL Line Configuration Profile Table, ( cvdslLineConfProfileTable ), which apply for this VDSL line, and channels if applicable.

The value of this object identifies the rows in the VDSL Line Alarm Configuration Profile Table, ( cvdslLineAlarmConfProfileTable ), which apply to this VDSL line, and channels if applicable.

This table provides one row for each Vtu. Each row contains the Physical Layer Parameters table for that Vtu. VDSL physical interfaces are those ifEntries where ifType is equal to vdsl(97).

An entry in the cvdslPhysTable.

Identifies whether the modem is the Vtuc or Vtur.

The vendor specific string that identifies the vendor equipment.

The vendor ID code is a copy of the binary vendor identification field defined by the PHY[10] and expressed as readable characters.

The vendor specific version number sent by this Vtu as part of the initialization messages. It is a copy of the binary version number field defined by the PHY[10] and expressed as readable characters.

Noise Margin as seen by this Vtu with respect to its received signal in tenth dB.

Measured difference in the total power transmitted by the peer Vtu and the total power received by this Vtu.

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. Bits: 'noPeerVtuPresent': 9, 'lossOfLink': 5, 'lossOfSignalQuality': 4, 'dataInitFailure': 6, 'noDefect': 0, 'configInitFailure': 7, 'protocolInitFailure': 8, 'lossOfFraming': 1, 'lossOfPower': 3, 'lossOfSignal': 2.

Measured total output power transmitted by this ATU. This is the measurement that was reported during the last activation sequence.

Indicates the maximum currently attainable data rate by the Vtu. This value will be equal or greater than the current line rate.

This table provides one row for each Vtu channel. VDSL channel interfaces are those ifEntries where ifType is equal to interleave(124) or fast(125).

An entry in the cvdslChanTable.

Interleave Delay for this channel. Interleave delay applies only to the interleave (slow) channel and defines the mapping (relative spacing) between subsequent input bytes at the interleaver input and their placement in the bit stream at the interleaver output. Larger numbers provide greater separation between consecutive input bytes in the output bit stream allowing for improved impulse noise immunity at the expense of payload latency. In the case where the ifType is fast(125), the object is not instantiated.

Indicates the length of the channel data-block on which the CRC operates.
