What Is CADANT-CMTS-EQUIPMENT-MIB?

CADANT-CMTS-EQUIPMENT-MIB is a vendor-specific MIB from Cadant (acquired by ARRIS) used to manage and monitor the hardware equipment of the Arris/Cadant E6 Cable Modem Termination System (CMTS) chassis used in cable broadband networks. It exposes hardware inventory and status data covering cards, ports, disk drives, disk volumes, and shelf-level objects, along with system clock, diagnostic test, and auditing configuration, plus a dedicated equipment trap group. In monitoring terms it directly supports hardware health monitoring -- tracking card and port presence/status, disk drive and volume health, and equipment-related fault traps with configurable severity (trapSeverity) -- making it central to detecting failed cards, degraded disks, or chassis-level faults on the CMTS, which is why CADANT-CMTS-EQUIPMENT-MIB SNMP monitoring is typically scheduled at short polling intervals on production chassis where hardware faults directly affect subscriber-facing service. It is a self-contained equipment MIB that works alongside other CADANT MIBs (such as CADANT-SHOWCM-FORMAT-MIB) covering cable-modem-specific functionality on the same platform. It would typically be deployed on Arris/Cadant E6 CMTS chassis at a cable operator's headend or hub site.

IPNetwork Monitor allows you to monitor SNMP objects defined in CADANT-CMTS-EQUIPMENT-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

  • Arris/Cadant E6 CMTS chassis

Monitoring Examples

An administrator would poll cardNumber and portNumber alongside the equipmentTraps group to detect when a line card or port has failed or been removed, and would check diskDriveNumber/diskVolumeNumber objects to confirm local storage health on the CMTS. The trapCounter and trapSeverity objects let an operator gauge how many equipment faults have fired and at what urgency, useful for prioritizing response to a chassis showing repeated high-severity equipment traps. systemClock would be checked to confirm the CMTS's internal clock is synchronized, since a drifted clock can skew trap timestamps during incident investigation.

What Can Be Monitored

  • card and port operational status
  • disk drive/volume health
  • equipment trap count and severity
  • system clock synchronization
  • shelf-level status

How to Use in IPNetwork Monitor

Example using cerCardTemperature OID:

Select an ARRIS/Cadant C4/E6000 CMTS 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 cerCardTemperature 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 card's relative temperature on a 1 (coolest) to 10 (hottest) scale. 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 Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value reaches 8 or higher on this relative scale, since sustained high relative temperature often precedes thermal shutdown or hardware degradation. Click Finish to create the monitor; you can adjust any parameter later.
