What Is ZTE-AN-EPON-SERVICE-MIB?

ZTE-AN-EPON-SERVICE-MIB manages service provisioning on ZTE access-node EPON (Ethernet Passive Optical Network) systems, covering ONU (Optical Network Unit) registration and service-flow configuration for subscribers connected via PON. It exposes categories of data including ONU registration/discovery state, per-subscriber service-flow definitions, and bandwidth/QoS parameters associated with those flows. Its monitoring value is centered on service and connectivity status: tracking ONU registration state reveals whether a subscriber's optical terminal is online and properly authenticated to the OLT, functioning as the software/connectivity-status equivalent of a link-up check for fiber-access subscribers. It builds on the IEEE 802.3ah/802.3av EPON standard for the underlying PON transport even though the service-provisioning objects are ZTE-proprietary. It is typically deployed by fiber broadband operators managing ZTE EPON access nodes (OLTs) serving residential/business ONUs, and these operators typically begin with a ZTE-AN-EPON-SERVICE-MIB download to load the module into their provisioning and monitoring tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZTE-AN-EPON-SERVICE-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 EPON OLT/access node
ZTE-compatible ONU (Optical Network Unit)

Monitoring Examples

An operator would poll ONU registration status to confirm a subscriber's ONU has successfully registered with the OLT after a fiber cut or power outage, and would check the associated service-flow configuration to verify the correct bandwidth profile was reapplied. A stuck 'unregistered' ONU state would point to an optical-signal or ranging problem on that PON port.

What Can Be Monitored

ONU registration/discovery status
service flow configuration per subscriber
bandwidth/QoS parameters per flow
PON port service state

How to Use in IPNetwork Monitor

Example using dot3EponFecPCSCodingViolation OID:

Select a ZTE EPON OLTs/ONU 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 dot3EponFecPCSCodingViolation 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. It reports the for 100 Mbps operation it is a count of the number of times an invalid code-group is received, other than the /H/ code-group. 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 Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

The entries in the table are control and status objects of the MPCP. Each object has a row for every virtual link denoted by the corresponding ifIndex. The LLID field, as defined in the [802.3ah] is a 2bytes register (15bits field and a broadcast bit) limiting the number of virtual links to 32768. Typically the number of expected virtual links in a PON is like the number of ONUs, which is 32-64, plus an additional entry for broadcast LLID (with a value of 0xffff).

A Row in the table is denoted by the ifIndex of the link and it is created when the ifIndex is created. The rows in the table for an ONU interface are created at system initialization. The row in the table corresponding to the OLT ifIndex and the row corresponding to the broadcast virtual link are created at system initialization. A row in the table corresponding to the ifIndex of a virtual links is created when a virtual link is established (ONU registers) and deleted when the virtual link is deleted (ONU deregisters).
