Description: Manages ZTE access node IGMP snooping, proxy, and multicast group membership for IPTV services.

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 ZTE-AN-IGMP-MIB?

ZTE-AN-IGMP-MIB belongs to ZTE's Access Node (AN) broadband access product line and manages IGMP snooping and proxy functions used to control multicast group delivery, most commonly for IPTV services. It exposes multicast group membership state and IGMP feature-compliance information for the device. Its monitoring value is primarily software/protocol-level: it reports which multicast groups are currently joined per subscriber port and which IGMP capabilities (snooping, proxy, versions) the agent supports, letting operators pinpoint why a subscriber isn't receiving a multicast video channel. It builds directly on the IETF IGMP standard (RFC 2236 and related versions) and complements the conformance-style structure seen in standard IGMP MIBs. It is typically deployed on DSLAM/OLT access nodes delivering IPTV over broadband access networks, and administrators can download the ZTE-AN-IGMP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZTE-AN-IGMP-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

  • ZTE access node (DSLAM/OLT broadband access platform)

Monitoring Examples

An operator would poll the zxAnIgmpGroups table to see the current multicast groups joined on a given subscriber port, checking group membership and timeouts to detect a subscriber who isn't receiving an expected IPTV channel. The zxAnIgmpCompliances object documents which IGMP snooping/proxy feature set and protocol version the device implements, which is useful for confirming interoperability before digging further into a channel-join failure.

What Can Be Monitored

  • IGMP snooping/proxy compliance level
  • multicast group membership per port
  • active multicast group count
  • IGMP feature/version support

How to Use in IPNetwork Monitor

Example using zxAnIgmpPktStatsRxCommQry OID:

Select a ZTE access node (DSLAM/OLT broadband access platform) (IGMP snooping/proxy multicast-group-membership 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 zxAnIgmpPktStatsRxCommQry 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 counter of IGMP general query message received. 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.
