Description: Huawei mDNS relay MIB for managing multicast DNS relay configuration and statistics across VLANs.
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 HUAWEI-MDNS-RELAY-MIB?
HUAWEI-MDNS-RELAY-MIB is a Huawei-proprietary MIB for Huawei switches that manages the multicast DNS (mDNS) relay feature, which forwards mDNS service-discovery traffic (such as Bonjour/AirPlay-style discovery) across VLAN boundaries that would normally block link-local multicast. Its data covers configuration objects for enabling mDNS relay per VLAN and statistics counters tracking the volume of mDNS packets relayed or dropped. Its monitoring value is primarily software/feature-status: confirming mDNS relay is enabled on the intended VLANs and reviewing relay statistics to see whether service-discovery traffic is actually being forwarded, which helps troubleshoot why devices on different VLANs cannot discover each other. It builds on the standard mDNS protocol (RFC 6762) for its packet semantics even though it is implemented as a Huawei-private relay feature. It is typically deployed on Huawei enterprise or campus access/aggregation switches in networks segmented into multiple VLANs where cross-VLAN service discovery (e.g., printers, AirPlay devices) is required. Engineers can download the HUAWEI-MDNS-RELAY-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-MDNS-RELAY-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
- Huawei enterprise/campus access and aggregation switches
Monitoring Examples
An administrator would check the per-VLAN mDNS relay enable/disable configuration objects and relay statistics counters to confirm mDNS traffic is being forwarded between two VLANs where users report devices are not discoverable across segments. No sample object names were provided for this module, so specific table names cannot be cited, but the module description confirms mDNS relay configuration and statistics as the scope. Relay statistics showing zero packets forwarded despite relay being enabled would indicate a configuration or multicast-routing problem preventing mDNS traffic from crossing VLANs.
What Can Be Monitored
- mDNS relay enable/disable status per VLAN
- mDNS packets relayed/dropped statistics
- cross-VLAN relay configuration
