What Is DECHUB900-HUBMGR-MIB-V3-0?

DECHUB900-HUBMGR-MIB-V3-0 is Digital Equipment Corporation's MIB for the hub management card that oversees the overall chassis in the DEChub 900 series multiswitch hub. It exposes an event log (eventLogTable/eventLogEntry with index, slot, timestamp, and description) recording chassis-wide events, and a hub alarm table (hubAlarmTable/hubAlarmEntry keyed by slot number and index) for tracking alarm conditions with configurable intervals, alongside a total event counter. It is used to monitor the overall hardware health of the hub chassis by watching for new alarm entries tied to specific slots and reviewing the event log's timestamped descriptions, which reveal module insertions/removals, faults, or other chassis-level events across the multiswitch backplane. It falls under the broader DEC enterprise MIB tree (dec, ema, decMIBextension) and is designed to be used alongside per-module MIBs for the individual switch/hub cards installed in each slot. It was deployed in enterprise LAN wiring closets using DEChub 900 multiswitch hubs to aggregate and manage multiple network modules from a single chassis. Engineers can download the DECHUB900-HUBMGR-MIB-V3-0 file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DECHUB900-HUBMGR-MIB-V3-0. 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

  • Digital Equipment Corporation (DEC) DEChub 900 multiswitch hub chassis

Monitoring Examples

An admin polls eventLogTable/eventLogEntry, checking eventLogTimeStamp and eventLogDescription against eventLogSlot to identify when and where a chassis event (such as a module reset) occurred, using eventLogTotalEvents to gauge overall event volume. Rising entries in hubAlarmTable/hubAlarmEntry, indexed by hubAlarmSlotNumber and hubAlarmIndex, with a given hubAlarmInterval, would flag a specific slot experiencing repeated alarm conditions. Correlating a spike in hubAlarmTable entries for one slot with a corresponding eventLogDescription entry helps pinpoint a failing module in the hub chassis.

What Can Be Monitored

  • chassis event log (slot, timestamp, description)
  • total event count
  • per-slot alarm entries and intervals
  • hub alarm indexing by slot
