Description: Provides basic system identification, software version, and controller health objects for Nortel NTWS WLAN platforms.

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 NTWS-BASIC-MIB?

NTWS-BASIC-MIB provides basic system identification and controller health objects for Nortel Networks' NTWS wireless LAN switch (WLAN controller) platform. It belongs to the Nortel enterprise wireless networking technology area. It exposes system-level identity data (serial number, software major/minor version, version string), mobility-domain configuration (domain name, seed IP, member table), and license inventory information. Its role in monitoring is centered on software/hardware identification and licensing status, tracking the controller's serial number and firmware version to confirm what is running, and the mobility domain member table to verify which controllers are peered, useful for detecting a firmware mismatch or an unexpectedly missing mobility domain member. It is a Nortel proprietary MIB not explicitly built on a specific IETF base standard, though it complements standard SNMP system group concepts. It is typically deployed on Nortel/Avaya wireless switch controllers managing groups of access points across a campus wireless network, where NTWS-BASIC-MIB SNMP monitoring confirms firmware version and mobility-domain membership consistency.

IPNetwork Monitor allows you to monitor SNMP objects defined in NTWS-BASIC-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

Nortel/Avaya NTWS wireless LAN switch controller

Monitoring Examples

An administrator would poll ntwsSerialNumber, ntwsSwMajorVersionNumber, ntwsSwMinorVersionNumber, and ntwsVersionString to confirm the exact firmware release running on a controller before or after an upgrade. Checking ntwsMobilityDomainName and ntwsMobilityMemberTable/ntwsMobilityMemberEntryAddr would reveal whether all expected controllers are present in the mobility domain, and a missing entry would indicate a peer controller has dropped out of the domain. The ntwsLicenseInfoTable would additionally be polled to confirm licensed feature/capacity counts remain within purchased limits.

What Can Be Monitored

controller serial number
software major/minor version
mobility domain membership
mobility domain seed IP
license inventory/capacity
version string

How to Use in IPNetwork Monitor

Example using ntwsMobilityMemberTableSize OID:

Select a Nortel/Avaya NTWS wireless LAN switch controller 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 ntwsMobilityMemberTableSize into the Find box to locate it in the OID tree, then select it and click OK. The number of entries in the mobility member table, ntwsMobilityMemberTable. 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 count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
