Description: Manages Very High Speed DSL (VDSL) line interfaces, providing configuration and monitoring of VDSL physical-layer parameters (RFC 3728).
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring VDSL-LINE-MIB with a free 30-day trial of IPNetwork Monitor.
What Is VDSL-LINE-MIB?
VDSL-LINE-MIB is an IETF standards-based MIB (RFC 3728) for managing Very High Speed Digital Subscriber Line (VDSL) physical-layer transceivers, applicable to any vendor's VDSL modem or DSLAM line card rather than a single manufacturer. It exposes configuration and physical-layer data for each VDSL line, including line coding, line type, configuration/alarm profiles, and per-transceiver physical inventory such as vendor ID and serial number, tracked per line-end (CO or CPE side) via vdslPhysSide. For monitoring, it lets an operator watch the software/configuration status of each line (profile assignment, coding mode) and hardware identity/inventory (transceiver vendor and serial number), which supports fault isolation when a line degrades or a transceiver is replaced/swapped unexpectedly. It is designed to require no management communication between the two line-end agents, relying instead on standard ifTable integration (IF-MIB) since each VDSL line appears as an interface. It is typically deployed on DSLAMs and VDSL customer-premises modems in broadband access networks, and an operator troubleshooting a single vdsl line typically polls this MIB per interface to confirm its coding and profile settings match provisioning intent.
IPNetwork Monitor allows you to monitor SNMP objects defined in VDSL-LINE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer, applies to DSLAMs and VDSL modems/transceivers
Monitoring Examples
An operator can poll vdslLineTable/vdslLineEntry for vdslLineCoding and vdslLineType to confirm a line's modulation and configuration profile (vdslLineConfProfile, vdslLineAlarmConfProfile) match provisioning intent, and detect drift after a firmware update. Querying vdslPhysTable/vdslPhysEntry with vdslPhysSide distinguishes the CO-end from the CPE-end transceiver on the same line, while vdslPhysInvVendorID and vdslPhysInvSerialNumber reveal the actual hardware installed -- useful for spotting an unauthorized or mismatched transceiver swap. Alarms surfaced under vdslNotifications combined with the alarm configuration profile indicate when a line has crossed a fault threshold.
What Can Be Monitored
- line coding/type
- configuration and alarm profiles
- per-side transceiver inventory (vendor ID, serial number)
- line alarms/notifications

How to Use in IPNetwork Monitor
Example using vdslPhysCurrSnrMgn OID:
Select a VDSL DSLAM or modem/transceiver as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type vdslPhysCurrSnrMgn into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the noise margin on this VDSL line's received signal, in units of 0.25 dB, as seen by the VTU. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drops below 24 (i.e. 6.0 dB), since low noise margin often precedes line errors or a lost DSL sync. Click Finish to create the monitor; you can adjust any parameter later.

| vdslMIB | 1.3.6.1.2.1.10.97 | The MIB module defining objects for the management of a pair of VDSL transceivers at each end of the VDSL line. Each such line has an entry in an ifTable which may include multiple transceiver lines. 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) transceiver at near (Central) end of line Vtur -- (VTUR) transceiver at Remote end of line Vtu -- One of either Vtuc or Vtur Curr -- Current Prev -- Previous Atn -- Attenuation ES -- Errored Second. SES -- Severely Errored Second UAS -- Unavailable Second LCS -- Line Code Specific Lof -- Loss of Frame Lol -- Loss of Link Los -- Loss of Signal Lpr -- Loss of Power xxxs -- Sum of Seconds in which xxx has occured (e.g., xxx = Lof, Los, Lpr, Lol) Max -- Maximum Mgn -- Margin Min -- Minimum Psd -- Power Spectral Density Snr -- Signal to Noise Ratio Tx -- Transmit Blks -- Blocks Copyright (C) The Internet Society (2004).

| BIT vdslPhysCurrStatus | 1.3.6.1.2.1.10.97.1.1.2.1.7 | Bits | read-only | 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.

FAQ
How does VDSL-LINE-MIB help isolate a degrading VDSL line between a DSLAM and a customer-premises modem?
It exposes line coding/type and configuration/alarm profile assignment per line, plus per-transceiver physical inventory such as vendor ID and serial number tracked per line-end (CO or CPE side), letting an operator confirm a line's settings still match provisioning intent or spot an unexpectedly swapped transceiver.
Does VDSL-LINE-MIB require the CO-side and CPE-side agents to communicate with each other for management?
No — it's designed to require no management communication beyond what's inherent in the VDSL line protocol itself, relying instead on each VDSL line appearing as a standard ifTable entry via IF-MIB.
