Description: Huawei multicast MIB for managing IP multicast routing, group membership, and multicast forwarding entries.

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-MULTICAST-MIB?

HUAWEI-MULTICAST-MIB is a Huawei-proprietary MIB for Huawei switches that manages IP multicast handling at Layer 2 via IGMP Snooping, the mechanism by which a switch listens to IGMP messages between hosts and multicast routers to selectively forward multicast traffic only to interested ports. Its data spans per-VLAN configuration (enabling IGMP snooping and proxy, query-source address, suppression timers) and operational objects reflecting the snooping feature's active state, such as whether snooping and proxy are currently enabled on a given VLAN. As a Layer-2 multicast-control feature its monitoring value is software/feature-status oriented: confirming IGMP snooping and query behavior are enabled where expected, which prevents multicast flooding to uninterested ports and reduces unnecessary bandwidth use across the switch. It is built directly on the standard IGMP protocol (used by IPv4 hosts to signal multicast group interest) referenced explicitly in the module description, layering Huawei-specific snooping controls on top of that IETF standard. It is typically deployed on Huawei access and aggregation switches in networks delivering IPTV or other multicast-based services where efficient, selective multicast forwarding at the switch is required, as exposed through the HUAWEI-MULTICAST-MIB MIB.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-MULTICAST-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 access/aggregation switches

Monitoring Examples

An administrator would check hwIgmpSnoopingEnabled and the per-VLAN hwVlanCfgTable/hwVlanCfgEntry (indexed by hwVlanIndex) to confirm hwVlanIgmpSnoopingEnabled is set correctly on VLANs carrying IPTV multicast traffic, and would review hwSendQueryEnabled and hwSendQuerySourceIpAddr to verify the switch is generating IGMP queries with the expected source address. If hwIgmpSnoopingSuppressionTime is misconfigured, redundant query suppression could cause slower convergence when a multicast source changes; checking hwIgmpProxyEnabled and hwIgmpSnoopingProxyEnabled would reveal whether the switch is proxying membership reports upstream as intended. A VLAN showing hwIgmpSnoopingEnabled true but no active group membership when clients are known to be watching multicast streams would point to a snooping or query-source misconfiguration.

What Can Be Monitored

  • IGMP snooping enable/disable status per VLAN
  • IGMP proxy enable/disable status
  • query source IP address and send-query status
  • snooping suppression timer
  • per-VLAN multicast configuration

How to Use in IPNetwork Monitor

Example using hwSystemRecvVlanUpEventTimes OID:

Select a Huawei access/aggregation switch (IGMP snooping) 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 hwSystemRecvVlanUpEventTimes into the Find box to locate it in the OID tree, then select it and click OK. The statistics of vlan up event. 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 Counter32-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.
