Description: Manages Zhone Technologies LAN device configuration including Ethernet ports, DHCP, and IP addressing.

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 ZHNLANDEVICE?

ZHNLANDEVICE defines private enterprise MIB extensions from Zhone Technologies for the LAN-side Ethernet, USB, WLAN, and MoCA interfaces on Zhone customer-premises equipment (CPE) such as residential/business gateways. It exposes categories of data including per-LAN-device Ethernet/USB/WLAN/MoCA interface counts and configuration, IGMP snooping settings for multicast control, DHCP/host configuration, and general IP interface objects. Its primary monitoring value is configuration and interface-state visibility rather than classic hardware sensors: an admin can confirm how many Ethernet, USB, wireless, or MoCA interfaces are present and active on the CPE, and whether IGMP snooping is correctly enabled for IPTV/multicast traffic. It builds on standard host-resources and IP-interface conventions (e.g., a lanHostConfigManagementObjects-style structure) reflecting typical broadband CPE management practice. It is typically deployed by broadband service providers to remotely manage Zhone residential/SMB gateways delivering triple-play (data/voice/video) service. Engineers can download the ZHNLANDEVICE file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZHNLANDEVICE. 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

  • Zhone Technologies residential/business gateway (CPE)
  • broadband router with Ethernet/WLAN/MoCA/USB interfaces

Monitoring Examples

An operator would poll lanDeviceTable/lanDeviceEntry (keyed by lanDeviceIndex) alongside lanEthernetInterfaceNumberOfEntries, lanWLANConfigurationNumberOfEntries, and lanMocaInterfaceNumberOfEntries to inventory which LAN interface types are provisioned on a given CPE unit. Checking igmpSnoopingCfgTable/igmpSnoopingCfgEntry (igmpEnable, igmpMode, igmpIfName) would reveal whether IGMP snooping is active on the LAN bridge, which is critical for diagnosing multicast/IPTV channel-change problems. A mismatch between expected and reported lanUSBInterfaceNumberOfEntries could indicate a failed or unrecognized USB peripheral on the gateway.

What Can Be Monitored

  • Ethernet/USB/WLAN/MoCA interface counts
  • LAN device inventory and index
  • IGMP snooping configuration
  • IGMP mode per interface
  • DHCP/host configuration
  • IP interface settings

How to Use in IPNetwork Monitor

Example using bytesSent OID:

Select a Zhone Technologies broadband gateway/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 bytesSent 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 total number of bytes sent over the interface since the CPE was last reset. 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 Gauge32-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.
