Description: Provides network maps and element inventory objects for the COM21 network management system.

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 COM21-NMAPS-MIB?

COM21-NMAPS-MIB is a Com21, Inc. (cable-modem/HFC access vendor) proprietary MIB defining trap fields for the NMAPS (Network Management Alert/Polling System) daemon monitoring Com21 cable-modem equipment. Its varbind objects cover an alert message string (application name, time, error number, description), MAC address, daemon name/PID, IP address, and a force-poll trigger. As a notification MIB it lets an administrator receive an application-level error alert identifying the affected cable modem's MAC/IP address on Com21 HFC access equipment. It is deployed on Com21, Inc. cable-modem/HFC access equipment. Engineers can download the COM21-NMAPS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in COM21-NMAPS-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

Com21, Inc. cable-modem/HFC access equipment

Monitoring Examples

An administrator reads nmapsAlertMessage and nmapsMacAddress from a received trap to identify the affected cable modem and error on Com21 HFC access equipment.

OIDs

OID symbolic	OID numeric	Type	Access	Description
NTF nmapsStuTopologyChange	1.3.6.1.4.1.1141.5.0.1			generated whenever it is suspected that a STU topology change has occured.
NTF nmapsStuDuplicateMac	1.3.6.1.4.1.1141.5.0.2			generated whenever two STU's with the same Mac Address are found on the same NMAPS.
NTF nmapsDaemonDown	1.3.6.1.4.1.1141.5.0.3			generated whenever the Hcx List application detects an NMAPS daemon has gone down.
NTF nmapsDaemonUp	1.3.6.1.4.1.1141.5.0.4			generated whenever the Hcx List application detects an NMAPS daemon has come up.
NTF nmapsUpdateHcxInDb	1.3.6.1.4.1.1141.5.0.5			A request to poll the HCX for current configuration and put the results in the NMAPS database.
NTF nmapsUpdateStusInDb	1.3.6.1.4.1.1141.5.0.6			A request to poll the Hcx for current STU configuration and put the results in the NMAPS database.
NTF nmapsConfiguredStuMissing	1.3.6.1.4.1.1141.5.0.7			generated whenever a configured STU is discovered to be missing from the ComCONTROLLER database. Either unconfiguration was done via a means other than NMAPS (e.g. CUI), or there is a bug.

NTF nmapsWarningAlert	1.3.6.1.4.1.1141.5.0.103			Generated when a Warning message is logged in the NMAPS Error Log.
NTF nmapsErrorAlert	1.3.6.1.4.1.1141.5.0.104			Generated when a Error message is logged in the NMAPS Error Log.
NTF nmapsFatalAlert	1.3.6.1.4.1.1141.5.0.105			Generated when a Fatal message is logged in the NMAPS Error Log.
NTF nmapsDisasterAlert	1.3.6.1.4.1.1141.5.0.106			Generated when a Disaster message is logged in the NMAPS Error Log.
