Description: Nokia Siemens Networks SHE DSLAM clock source and timing synchronization management, including SSM quality levels and configurable sync source tables

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SHE-SYNC-MIB?

SHE-SYNC-MIB is a Nokia Siemens Networks module for the SHE DSLAM platform that manages the network element's clock sources and timing synchronization. It models configurable synchronization source selection along with quality indicators such as SSM (Synchronization Status Message) quality levels, which describe how trustworthy a given timing reference is. Its monitoring value is squarely about a piece of critical infrastructure health: administrators use it to confirm the DSLAM is locked to an acceptable timing reference, detect a fallback to a lower-quality or holdover clock source, and catch timing source failures that could otherwise degrade services relying on synchronized transport. Timing/synchronization concepts here align with standard telecom synchronization quality signaling (SSM) conventions, though this module implements them in a vendor-specific table rather than importing a standard MIB directly. It is deployed on Nokia Siemens Networks SHE DSLAMs in access networks where accurate network timing is required for services such as bonded/multiplexed transport. Network engineers evaluating or troubleshooting this functionality can download the SHE-SYNC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SHE-SYNC-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.

Monitoring Examples

No object/table names were retained in this extract, so a concrete polling walk cannot be grounded in real identifiers here; based on its stated purpose, an administrator would typically poll the current synchronization source selection and its SSM quality level, since a drop to a lower quality level or an unexpected source switchover would indicate the primary timing reference has degraded or failed.

What Can Be Monitored

active synchronization source
SSM timing quality level
configured sync source table
sync source switchover events
