Description: Manages system-level configuration including software version, boot parameters, and system identity on ARRIS/Cadant CMTS equipment.

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 CADANT-CMTS-SYSTEM-MIB?

CADANT-CMTS-SYSTEM-MIB is an ARRIS proprietary MIB (successor to the Cadant name) defining system-wide DOCSIS timing and protocol parameters and constants on the Arris E6000 CMTS. Its objects configure synchronization interval, UCD (Upstream Channel Descriptor) interval, maximum pending MAPs, ranging interval, ranging/registration retry limits, and per-message processing-time constants used in DOCSIS cable-modem registration. As a configuration MIB it lets an administrator confirm the CMTS's DOCSIS timing parameters match vendor-recommended values when diagnosing cable-modem registration delays or failures. It is deployed on ARRIS E6000 CMTS platforms in cable operator head-ends. Engineers can download the CADANT-CMTS-SYSTEM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CADANT-CMTS-SYSTEM-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 E6000 CMTS

Monitoring Examples

An administrator checks cadSysRangingInterval and cadSysInvitedRangingRetries against recommended DOCSIS timing values when a batch of cable modems is taking unusually long to complete ranging and registration.

What Can Be Monitored

  • DOCSIS timing intervals and registration retry limits

How to Use in IPNetwork Monitor

Example using cadSysProcRouterControlGlobalPacketsReceivedPassed OID:

Select an ARRIS E6000 CMT 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 cadSysProcRouterControlGlobalPacketsReceivedPassed into the Find box to locate it in the OID tree, then select it and click OK. The number of packets received passed to the Router Control processor. 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 Counter32-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 (in packets), 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.
