Description: Alcatel-Lucent 7x50 service router MIB for managing IGMP snooping on service access points, SDP bindings, and multicast group filter policies

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 ALCATEL-IGMP-SNOOPING-MIB?

ALCATEL-IGMP-SNOOPING-MIB is an Alcatel-Lucent proprietary MIB for the 7x50 family of service routers, covering configuration and management of IGMP snooping — the feature that lets a service router intelligently forward IP multicast traffic only to interested ports. It exposes per-service configuration objects including administrative state, query interval, robustness count, and Multicast VLAN Registration (MVR) settings, along with policy objects controlling which multicast groups are permitted. Its monitoring role centers on multicast service configuration and operational state rather than classic hardware health: operators use it to verify IGMP snooping is administratively enabled where expected, confirm query timer and robustness settings match network design, and track when configuration last changed. It is closely tied to IETF IGMP (RFC 3376) and to Alcatel-Lucent's own service/SAP object model (VPLS/TLS service framework) that it plugs into. It is deployed on Alcatel-Lucent (Nokia) 7x50 service routers in triple-play/IPTV and enterprise multicast deployments where efficient multicast distribution over Ethernet VPLS services is required, and an ALCATEL-IGMP-SNOOPING-MIB download is available for administrators who need to load it directly into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-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

  • Alcatel-Lucent (Nokia) 7x50 service routers

Monitoring Examples

An administrator would poll tlsIgmpSnpgConfigTable/tlsIgmpSnpgConfigEntry per service to confirm tlsIgmpSnpgCfgAdminState is enabled and that tlsIgmpSnpgCfgGenQueryIntvl and tlsIgmpSnpgCfgRobustCount are set per the network's multicast design. Checking tlsIgmpSnpgCfgLastChangeTime helps correlate a reported IPTV channel-join problem with a recent, possibly unintended, configuration change, while tlsIgmpSnpgCfgMvrAdminState and tlsIgmpSnpgCfgMvrPolicy reveal whether Multicast VLAN Registration is active and which policy governs it.

What Can Be Monitored

  • IGMP snooping admin state per service
  • query interval and robustness count
  • multicast VLAN registration (MVR) state/policy
  • configuration last-change timestamp

How to Use in IPNetwork Monitor

Example using sapIgmpSnpgTxGenQueries OID:

Select an Alcatel-Lucent (Nokia) 7x50 service router as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type sapIgmpSnpgTxGenQueries into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The value of the object sapIgmpSnpgTxGenQueries indicates the number of IGMP General Queries transmitted on this SAP. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
