What Is DSLAM-BACKUP-MIB?
DSLAM-BACKUP-MIB is a private MIB module for managing backup and redundancy configuration on DSL Access Multiplexer (DSLAM) equipment used in DSL broadband access networks. Based on its stated purpose it exposes configuration objects that control failover behavior between redundant DSLAM control/line cards or chassis, rather than a broad range of interface or traffic counters. Its monitoring value centers on hardware and system resiliency status: which unit is currently active vs. standby, whether a backup/redundant unit is present and healthy, and whether a failover event has occurred, which are the key signals an operator needs to confirm backup protection is actually working. No module description detail or sample object list was available in the source, so finer-grained object names cannot be confirmed. It is deployed on carrier DSL access equipment in central offices where DSLAM redundancy is used to avoid single points of failure for subscriber DSL service, making the DSLAM-BACKUP-MIB reference useful for operators verifying redundant hardware protection during central-office audits.
IPNetwork Monitor allows you to monitor SNMP objects defined in DSLAM-BACKUP-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
- PairGain Technologies DSLAM (backup/redundancy) — Identified as PairGain Technologies via the module's own ORGANIZATION field, not 'vendor not identified' as previously described — consistent with sibling modules DSLAM-FLASH-MIB and DSLAM-UPC-MIB (also PairGain).
Monitoring Examples
With no sample objects provided in the source, specific object names cannot be confirmed; based on the module's stated purpose an admin would typically poll a redundancy/backup status object to determine which DSLAM unit (primary or backup) is currently active and whether the standby unit is healthy and ready. A change from active to failed-over status would indicate the primary DSLAM card or chassis has failed and traffic has switched to backup, which is the scenario this MIB is designed to expose.
What Can Be Monitored
- active/standby redundancy state
- backup unit presence/health
- failover event occurrence
