Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DASAN-ACCESS-SLOT-H248-MIB?

DASAN-ACCESS-SLOT-H248-MIB is a DASAN Networks MIB for managing H.248 (Megaco) VoIP gateway slot configuration on DASAN access aggregation platforms. Although no sample objects were extracted for this module, its module description confirms it is part of the vendor's Access Gateway Management Information Base, indicating it exposes per-slot H.248 media gateway configuration such as media gateway controller (MGC) associations, termination/context settings, and slot-level VoIP gateway parameters. It would be used to monitor the software/service status of the H.248 gateway function per slot, confirming a VoIP gateway card has successfully registered with its media gateway controller and that its H.248 signaling session remains active, which is critical for detecting a VoIP service outage on that slot. It likely depends on standard H.248/Megaco protocol conventions and on the chassis's slot/card inventory conventions shared across DASAN access platform MIBs. It was deployed on DASAN Networks access gateway/DSLAM-style platforms delivering VoIP services alongside broadband access. Engineers can download the DASAN-ACCESS-SLOT-H248-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DASAN-ACCESS-SLOT-H248-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

Because sample objects were not available for this module, exact OID names must be confirmed from the vendor source, but a plausible monitoring scenario involves polling a per-slot H.248 status table to confirm each VoIP gateway card's registration state with its media gateway controller. A slot reporting an unregistered or failed H.248 association would indicate a VoIP service outage for subscribers served by that card, prompting a card reset or MGC connectivity check. Monitoring across all slots in a chassis lets an operator quickly identify which specific card lost its signaling session during a network event.

What Can Be Monitored

per-slot H.248 gateway registration status
media gateway controller association
VoIP signaling session state
slot configuration status
