Description: Broadcom FastPath MIB for IP multicast routing and IGMP/MLD snooping configuration on FastPath-based 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.

What Is FASTPATH-MULTICAST-MIB?

FASTPATH-MULTICAST-MIB is part of Broadcom's FastPath switch software MIB family, covering the Multicast Routing 'Flex package' -- IP multicast routing plus IGMP/MLD snooping configuration. It exposes the switch's multicast-handling behavior, including which ports and VLANs participate in multicast group forwarding and how snooping is configured. Its role in device monitoring is primarily software/service-level: verifying that multicast forwarding and snooping are enabled and functioning correctly is essential to diagnosing problems like multicast traffic flooding (snooping not working) or a client failing to receive a stream (forwarding misconfigured), both of which affect services such as IPTV or multicast video conferencing. It builds on standard IGMP/MLD concepts and likely complements other IETF multicast-routing MIBs, while remaining part of Broadcom's proprietary FastPath enterprise tree alongside sibling FASTPATH-* modules. It is deployed on FastPath-chipset-based switches (used by various OEM and white-box switch vendors) in enterprise and datacenter LANs carrying multicast traffic. Engineers can download the FASTPATH-MULTICAST-MIB file directly to load it into their MIB browser.

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

FastPath (Broadcom-chipset) based switches

Monitoring Examples

No specific object or table names were provided for this module, so a concrete polling example grounded in real identifiers cannot be given here; conceptually, though, an administrator managing multicast routing and IGMP/MLD snooping on a FastPath switch would check whether snooping is enabled on the relevant VLANs and inspect multicast group membership to confirm a stream is being forwarded only to the ports that requested it.

What Can Be Monitored

IGMP/MLD snooping enable status
multicast group membership per VLAN/port
multicast routing table entries
multicast traffic forwarding state
