ZYXEL-IGMP-FILTER-MIB

Description: Manages ZyXEL IGMP filter profiles to control multicast group membership per port on access 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.

ZYXEL-IGMP-FILTER-MIB is a ZyXEL enterprise MIB defining the subtree for IGMP filter profiles, a feature that restricts which multicast groups a switch port may join, commonly used to prevent unauthorized IPTV or multicast stream access. It exposes configuration objects such as filter profile definitions, allowed/denied multicast group ranges, and per-port profile assignment. Its runtime monitoring value centers on verifying policy enforcement: administrators can check which filter profile is bound to a port and whether attempted joins to disallowed groups are blocked, a software/configuration-status check rather than a hardware health check. It shares port-indexing conventions with the switch's IF-MIB and works together with the ZyXEL IGMP snooping MIB, since filtering operates on groups discovered via snooping. It is deployed on ZyXEL access switches in service-provider or enterprise IPTV/multicast video deployments requiring per-subscriber or per-port multicast access control. Engineers can download the ZYXEL-IGMP-FILTER-MIB file directly to load it into their MIB browser.

No sample objects were provided, but a MIB of this design would typically define an IGMP filter profile table and a per-port profile-binding table keyed by profile ID and port index. An administrator would poll the port-binding table to confirm the correct filter profile is applied to a given port, investigating if a subscriber reports being unable to join an authorized multicast stream.
