Description: Manages World Wide Packets IGMP snooping querier settings, group tables, 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 WWP-IGMP-SNOOP-MIB?

WWP-IGMP-SNOOP-MIB is a World Wide Packets (WWP) proprietary MIB implementing IGMP snooping on WWP Ethernet switching products, a feature that lets a switch track multicast group membership to forward multicast traffic only to interested ports. It exposes IGMP snooping querier settings, learned multicast group membership tables, and multicast forwarding entries per VLAN/port. This is chiefly a protocol/configuration-state MIB: monitoring it lets an administrator confirm the IGMP querier is active, see which multicast groups are currently learned on which ports, and verify forwarding entries match expected multicast subscribers -- a software/protocol health check for multicast delivery rather than physical hardware status. It builds on the standard IGMP protocol (RFC 3376) and IGMP-snooping concepts, though implemented here as a WWP proprietary extension. It is typically deployed on World Wide Packets Ethernet access/aggregation switches in carrier Ethernet or metro networks that carry multicast video or other multicast services. Engineers can download the WWP-IGMP-SNOOP-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

No sample objects were provided for this module. An administrator would typically poll the IGMP snooping group membership table to confirm expected multicast groups are learned on the correct ports, and check querier status to ensure IGMP snooping is actively managing multicast forwarding, though specific object names cannot be cited here.

What Can Be Monitored

IGMP snooping querier status
learned multicast group membership
multicast forwarding entries per port/VLAN

wwpIgmpSnoop	1.3.6.1.4.1.6141.2.10.1.1
T/F wwpIgmpSnoopActivate	1.3.6.1.4.1.6141.2.10.1.1.1	TruthValue	read-write	Activate the Igmp Snooping operation with a value of True(1) or stop it with False(2).
wwpIgmpSnoopTable	1.3.6.1.4.1.6141.2.10.1.1.2		not-accessible	The (conceptual) table listing the IP multicast groups for which there are members on particular vlans.
wwpIgmpSnoopEntry	1.3.6.1.4.1.6141.2.10.1.1.2.1		not-accessible	An entry (conceptual row) in the wwpIgmpSnoopTable.
VLA wwpIgmpSnoopVlanId	1.3.6.1.4.1.6141.2.10.1.1.2.1.1	VlanId	read-only	The vlan for which this entry contains information for an IP multicast group address.
IP wwpIgmpSnoopGroupAddress	1.3.6.1.4.1.6141.2.10.1.1.2.1.2	IpAddress	read-only	The IP multicast group address for which this entry contains information.
POR wwpIgmpSnoopActivePorts	1.3.6.1.4.1.6141.2.10.1.1.2.1.3	PortList	read-only	The Port Map of the active ports for the igmp filter indexed by wwpIgmpSnoopVlanId and wwpIgmpSnoopGroupAddress.
I32 wwpIgmpSnoopRouterPort	1.3.6.1.4.1.6141.2.10.1.1.2.1.4	Integer32	read-only	The router port from which the igmp query messages are received, and joins/leaves messages are sent.
TIK wwpIgmpSnoopQueryTime	1.3.6.1.4.1.6141.2.10.1.1.2.1.5	TimeTicks	read-only	The time at which the last activity was observed on this stream.
I32 wwpIgmpSnoopLingerTimeout	1.3.6.1.4.1.6141.2.10.1.1.3	Integer32	read-write	This value specifies the amount of time that a multicast filter will be in place after the last host has left. In essence it configures how long to filter the stream after all the hosts have left the group. This can tune the system as to how long the router has to remove the stream from the subnet. The minimum value is 1 second, with no maximum value.
I32 wwpIgmpSnoopExpiryTimeout	1.3.6.1.4.1.6141.2.10.1.1.4	Integer32	read-write	The interval of time for which an igmp protocol entry, is allowed to remain valid without any activity.

If this object is set to 'inquisitive(2)', then a Group Specific Query is created for the multicast stream for which the leave was received. If no membership report is received in the time interval configured by the wwpIgmpSnoopInqLeaveTimeout, then the multicast stream is pruned.

The inquisitive leave timer is started only when the wwpIgmpSnoopLeaveMode is set to 'inquisitive(2)'.
