Description: Manages MLD and IGMP snooping for IPv4/IPv6 multicast on D-Link switches.

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 DLINKSW-MGMD-SNOOPING-MIB?

This is a D-Link proprietary MIB module for Multicast Group Membership Discovery (MGMD) snooping on the DLINKSW switch line, covering both MLD (IPv6) and IGMP (IPv4) multicast snooping. It defines configuration and status objects for tracking which VLANs and ports are participating in multicast group membership as learned through protocol snooping. Its monitoring focus is on the software-level multicast forwarding state: administrators verify snooping is enabled and correctly tracking group membership per VLAN and port, which helps catch multicast flooding caused by a snooping failure or a misconfigured VLAN, particularly important in IPTV or video conferencing deployments. It functions as a vendor-specific implementation alongside standard IGMP-MIB and IPv6 MLD mechanisms rather than superseding them. It is deployed on D-Link managed switches wherever multicast traffic needs to be efficiently constrained to only the ports that have requested it. Engineers can download the DLINKSW-MGMD-SNOOPING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINKSW-MGMD-SNOOPING-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.

D-Link managed switches

Monitoring Examples

Because no sample objects were provided, a typical monitoring approach mirrors other D-Link snooping MIBs: polling per-VLAN snooping enable/operational status and port-level multicast group membership tables to confirm a receiver port is correctly registered for an active multicast stream. An admin observing unexpected multicast flooding on a non-subscribed port would check this MIB's membership tables to determine whether IGMP or MLD snooping failed to properly track that port's group membership.

What Can Be Monitored

per-VLAN IGMP/MLD snooping status
port-level multicast group membership
IPv4 and IPv6 multicast traffic constraint

How to Use in IPNetwork Monitor

Example using dMgmdSnpStatPortIfV1RxReport OID:

Select a D-Link managed switch 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 dMgmdSnpStatPortIfV1RxReport 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. This indicates the number of MGMD v1 Report packets received in this port/port-channel. 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 a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
