Description: TIMETRA-MLD-SNOOPING-MIB module

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 TIMETRA-MLD-SNOOPING-MIB?

TIMETRA-MLD-SNOOPING-MIB is part of Nokia/Alcatel-Lucent's TIMETRA enterprise MIB family, managing the MLD (Multicast Listener Discovery, IPv6 multicast) snooping feature per service on SROS routers. It exposes tlsMldSnpgConfigTable with per-service admin state, general-query interval, robustness count, and query/report source addressing, plus MVR (multicast VPN routing) admin state. It is used to monitor software/configuration status of IPv6 multicast delivery: tlsMldSnpgCfgAdminState reveals whether snooping is actually enabled on a given service, and a misconfigured tlsMldSnpgCfgGenQueryIntvl or robustness count can explain subscribers failing to join or promptly leave multicast groups. It complements the IETF MLD protocol (RFC 2710) and Alcatel-Lucent's TLS (Transparent LAN Service)/VPLS bridging MIBs on which it operates. It is deployed on Nokia SROS routers delivering metro Ethernet IPTV or other IPv6 multicast services. Engineers can download the TIMETRA-MLD-SNOOPING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-MLD-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

  • Nokia/Alcatel-Lucent SROS routers delivering IPTV/multicast VPLS services

Monitoring Examples

An admin would poll tlsMldSnpgConfigTable per service and check tlsMldSnpgCfgAdminState is enabled where multicast video is expected; a service showing admin state down would explain subscriber complaints of missing channels. tlsMldSnpgCfgGenQueryIntvl and tlsMldSnpgCfgRobustCount would be reviewed to confirm query timing matches expected join/leave latency. tlsMldSnpgCfgQuerySrcAddr and tlsMldSnpgCfgMvrAdminState would be checked to verify the query source and MVR settings are consistent across the service.

What Can Be Monitored

  • MLD snooping admin state per service
  • general query interval
  • robustness count
  • query/report source address
  • MVR admin state

How to Use in IPNetwork Monitor

Example using sapMldSnpgTxGenQueries OID:

Select a Nokia/Alcatel-Lucent SROS routers delivering IPTV/multicast VPLS service (MLD snooping per-service admin status) 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 sapMldSnpgTxGenQueries 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 sapMldSnpgTxGenQueries indicates the number of MLD 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.
