Description: Manages ZyXEL IGMP snooping for efficient multicast forwarding by monitoring group join and leave messages.

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 ZYXEL-IGMP-SNOOPING-MIB?

ZYXEL-IGMP-SNOOPING-MIB is a ZyXEL enterprise MIB covering the subtree for IGMP snooping, the switch feature that inspects IGMP join/leave messages to forward multicast traffic only to ports with interested receivers rather than flooding it everywhere. It exposes configuration data (enabling/disabling snooping per VLAN, querier settings) plus dynamic operational data such as the learned multicast group membership per port/VLAN. This gives it clear value for monitoring software-level status: administrators can verify which ports actively belong to which multicast groups in real time, helping diagnose IPTV/streaming delivery problems or unexpected multicast flooding. It is closely related to the ZyXEL IGMP filter MIB, since filtering policies act on groups this MIB discovers, and it builds on standard VLAN and IF-MIB port-indexing conventions. It is deployed on ZyXEL Layer 2 access switches carrying IP multicast traffic such as IPTV, video conferencing, or market-data feeds. Engineers can download the ZYXEL-IGMP-SNOOPING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZYXEL-IGMP-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.

Supported Devices

  • ZyXEL managed Layer 2/Layer 3 switch

Monitoring Examples

No sample objects were provided, but such a MIB typically defines a multicast group membership table keyed by VLAN and port index, showing which multicast groups each port currently belongs to. An administrator would poll this table to confirm a client's IGMP join was correctly snooped and the corresponding port is included in that group's forwarding entry; an absence would explain a client not receiving a multicast stream.

What Can Be Monitored

  • IGMP snooping enable state per VLAN
  • learned multicast group membership per port
  • IGMP querier status
