Description: D-Link multicast proxy MIB providing objects for configuring IGMP/MLD proxy functionality on D-Link network devices.
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 MCAST-PROXY-MIB?
This is a D-Link enterprise MIB for configuring IGMP (IPv4) and MLD (IPv6) multicast proxy functionality on D-Link network devices, in the multicast-routing technology area. It exposes configuration objects controlling how the device proxies group-membership reports upstream on behalf of downstream hosts, rather than physical hardware data. Its monitoring value is largely about verifying multicast-proxy software configuration and operational state per interface or VLAN, which is essential when diagnosing failed or degraded IPTV/multicast-stream delivery. It is a vendor-proprietary companion to the standard IGMP/MLD protocols rather than a dependency-driven extension of another specific IETF MIB. It is deployed on D-Link managed switches/routers in networks carrying multicast applications such as IPTV or streaming media. Engineers can download the MCAST-PROXY-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in MCAST-PROXY-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
- D-Link managed switch/router
- vendor-specific (D-Link) network device
Monitoring Examples
No specific object or table names were provided in this excerpt (sample_objects is empty), so a grounded polling example cannot be constructed; in general terms an operator would check whether IGMP/MLD proxying is enabled on a given interface or VLAN and confirm the proxy's upstream/downstream interface assignment when multicast streams fail to reach subscribers.
What Can Be Monitored
- IGMP proxy enable/disable state
- MLD proxy enable/disable state
- proxy upstream/downstream interface assignment
