HPN-ICF-LswIGSP-MIB

Description: Manages IGMP snooping (IGSP) group membership and querier configuration on HP/Comware Layer 2 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.

HPN-ICF-LswIGSP-MIB is an HPE/H3C Comware ICF private MIB (LAN switch scope) that manages IGMP snooping (IGSP) group membership and querier configuration for controlling multicast traffic flooding on Layer 2 switches. No module description or object list is populated in this snapshot, but an IGMP snooping MIB of this type typically exposes a global/per-VLAN enable scalar, a multicast group membership table mapping group addresses to member ports, and querier configuration/status objects. Its monitoring focus is multicast software behavior: confirming snooping is enabled where expected and that the membership table accurately reflects ports with active receivers, preventing unnecessary flooding of multicast traffic. A membership table that fails to reflect an actively subscribed host would indicate an IGMP snooping malfunction impacting multicast delivery (e.g., IPTV). It complements the standard IGMP protocol (RFC 3376) with switch-local snooping state, and HPN-ICF-LswIGSP-MIB SNMP monitoring is typically deployed on HPE/H3C Comware Layer 2 switches carrying multicast traffic.

No object names are available in this snapshot, so a specific polling scenario cannot be given with confidence. Typically an operator would poll the IGMP snooping group membership table per VLAN to confirm which ports are registered receivers for a given multicast group, where a port known to be running an IPTV client missing from the table would explain undelivered multicast video traffic.
