Description: Manages ZTE ZXR10 Multi-link PPP bundle configuration, member links, and aggregated channel statistics.

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 ZXR10-MPPP-MIB?

ZXR10-MPPP-MIB is a ZTE proprietary MIB for the ZXR10 (ZXROSng) router/switch platform, covering Multilink PPP (MLPPP) bundle configuration — the technique of aggregating multiple physical serial/PPP links into a single logical higher-bandwidth channel. It exposes a member-link table describing each physical link's association with its master (bundle) port, including master/physical port names and indices, per-member interface operational state, and Endpoint Discriminator (EPD) configuration used for multilink fragment reassembly, plus a multilink bundle table for the aggregate itself. Its monitoring value is centered on link-aggregation health: operators track the member interface state to see if any physical link in the bundle has gone down, reducing available bandwidth without necessarily dropping the whole bundle, and verify EPD consistency between local and remote ends to catch multilink negotiation mismatches. It builds on the IETF Multilink PPP standard (RFC 1990) that defines the MLPPP bundling and fragment-reassembly mechanism this MIB manages. It is deployed on ZTE ZXR10 routers used in WAN aggregation scenarios where multiple lower-speed serial/PPP circuits are bonded for additional bandwidth or resiliency, and a ZXR10-MPPP-MIB download lets operators confirm every member link in a bundle stays up.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZXR10-MPPP-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

An operator would poll zxr10MpppMemberTable/zxr10MpppMemberEntry, keyed by zxr10MpppMemberMasterPortIndex and zxr10MpppMemberPhysicalIndex, to check zxr10MpppMemberIfState for each physical link in a bundle and detect that one member link has dropped out of an otherwise-up multilink bundle. Checking zxr10MpppMemberRowStatus alongside zxr10MpppMultilinkTable/zxr10MpppMultilinkEntry would confirm whether a newly added or removed member link has been properly committed to the bundle's active configuration, and comparing zxr10MpppMemberConfigEPD to zxr10MpppMemberRemoteEPD would help diagnose a bundle failing to form due to an endpoint-discriminator mismatch.

What Can Be Monitored

multilink PPP bundle member link status
member-to-bundle (master port) association
endpoint discriminator (EPD) configuration/match

How to Use in IPNetwork Monitor

Example using zxr10MpppMemberIfState OID:

Select a ZTE ZXR10 (ZXROSng) router (Multilink PPP member-link/EPD-consistency 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 zxr10MpppMemberIfState 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 mppp member ifstate. 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 an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'active', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.
