Description: Covers configuration and performance monitoring of HDSL2 and G.SHDSL line interfaces, both symmetric high-bit-rate DSL technologies.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring HDSL2-SHDSL-LINE-MIB with a free 30-day trial of IPNetwork Monitor.
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.
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.
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

How to Use in IPNetwork Monitor
Example using hdsl2ShdslEndpointCurrAtn OID:
Select a device implementing HDSL2-SHDSL-LINE-MIB 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 hdsl2ShdslEndpointCurrAtn 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 current loop attenuation, in dB, measured on this SHDSL line endpoint. 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 attenuation exceeds 40 dB, which typically signals a marginal or degrading copper line. Click Finish to create the monitor; you can adjust any parameter later.

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.
