What Is HDSL2-SHDSL-LINE-MIB?
HDSL2-SHDSL-LINE-MIB is a vendor-neutral IETF standards MIB (RFC 4319) for managing HDSL2 and G.SHDSL symmetric DSL line interfaces, which may reside on either end of the copper line. It exposes span configuration (profile, alarm profile) and status tables covering repeater count, maximum attainable vs. actual line rate, transmission mode, and payload rate. It is used to monitor line-level performance/hardware status — actual vs. maximum attainable line/payload rates reveal degraded copper line conditions, and the alarm profile/status tables surface line faults, directly supporting fault and performance monitoring of the DSL modem hardware. As a standards MIB it typically depends on/complements the DS1/E1 and IF-MIB frameworks for underlying transport layer status. It is deployed on DSL modems, DSLAMs, and routers with integrated HDSL2/SHDSL interfaces in telecom access and enterprise WAN environments, and engineers consulting an HDSL2-SHDSL-LINE-MIB reference will find these span and status tables documented alongside the RFC 4319 object definitions.
IPNetwork Monitor allows you to monitor SNMP objects defined in HDSL2-SHDSL-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.
What Can Be Monitored
- actual vs. maximum attainable line rate
- actual vs. maximum payload rate
- number of available repeaters
- current transmission mode
- span alarm profile
- span configuration profile
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer — applies to DSL modems/DSLAMs/routers with HDSL2 or G.SHDSL line interfaces
Monitoring Examples
An admin polls hdsl2ShdslSpanStatusTable/hdsl2ShdslSpanStatusEntry to compare hdsl2ShdslStatusActualLineRate against hdsl2ShdslStatusMaxAttainableLineRate, revealing whether the line is running below its potential rate due to noise or distance. hdsl2ShdslStatusNumAvailRepeaters and hdsl2ShdslStatusTransmissionModeCurrent give additional context on line topology and mode, while hdsl2ShdslSpanConfAlarmProfile (from hdsl2ShdslSpanConfTable) defines the thresholds used to raise line alarms.

The default value of this object is a zero-length SnmpAdminString. Any attempt to set this object to a value that is not the value of the index for an active entry in the profile table, hdsl2ShdslEndpointAlarmConfProfileTable, MUST be rejected. |

The various bit positions are as follows: noDefect There are no defects on the line. powerBackoff Indicates enhanced Power Backoff. deviceFault Indicates that a vendor-dependent diagnostic or self-test fault has been detected. dcContinuityFault Indicates vendor-dependent conditions that interfere with span powering such as short and open circuits. snrMarginAlarm Indicates that the SNR margin has dropped below the alarm threshold. loopAttenuationAlarm Indicates that the loop attenuation exceeds the alarm threshold. loswFailureAlarm Indicates a forward LOSW alarm. configInitFailure Endpoint failure during initialization due to paired endpoint not able to support requested configuration. protocolInitFailure Endpoint failure during initialization due to incompatible protocol used by the paired endpoint. noNeighborPresent Endpoint failure during initialization due to no activation sequence detected from paired endpoint. loopbackActive A loopback is currently active at this segment endpoint.

FAQ
What can HDSL2-SHDSL-LINE-MIB tell me about a degraded DSL line?
It provides span status tables reporting both maximum attainable and actual line rate as well as payload rate, so comparing these values reveals when a copper HDSL2/SHDSL line is running below its potential due to line degradation.
How is this MIB used to monitor DSL modem hardware faults?
It exposes repeater count, transmission mode, and alarm/configuration profile objects for each span, so an unexpected transmission mode or an alarm profile change surfaces line faults on the DSL modem, DSLAM, or router hardware.
