Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ASCEND-LANMODEM-MIB?

ASCEND-LANMODEM-MIB is an Ascend Communications (later Lucent) proprietary MIB reporting internal LAN-modem resource allocation and health across an Ascend access-server chassis. Its objects cover a slot-modem table (index, slot/item index, item status/status-character/config), available-modem tables (per slot/port used/bad counts, last-32-calls bitmask), suspect-modem tables with the same fields, and a disabled-modem list. As a hardware-status MIB it lets an administrator identify which internal modem resources are marked suspect or disabled due to repeated call failures on an Ascend access server. It is deployed on Ascend Communications (Lucent) access-server chassis. Engineers can download the ASCEND-LANMODEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-LANMODEM-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

Ascend Communications (Lucent) access-server chassis

Monitoring Examples

An administrator checks suspectLanModemBadCount to identify a failing internal modem resource on an Ascend access-server chassis before it degrades dial-in call quality.
