Description: ARRIS C3 CMTS upstream ranging process configuration and cable modem ranging statistics.
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 ARRIS-C3-RANGING-MIB?
This is an ARRIS enterprise MIB for the C3 CMTS (Cable Modem Termination System) platform, managing the DOCSIS upstream ranging process handled by the device's FFT-based ranging software. It exposes configuration and statistics related to cable modem upstream ranging, the process by which modems synchronize timing, power, and frequency with the CMTS upstream receiver. Its monitoring focus is squarely on the software/signal-processing health of the ranging subsystem, letting operators track ranging success/failure rates and per-modem ranging status, which is a leading indicator of upstream RF plant problems. It complements the standard DOCSIS interface MIBs used for broader cable-modem and CMTS interface monitoring. It's typically deployed on ARRIS C3 CMTS chassis in cable operator headends managing DOCSIS upstream channels, and operators can download the ARRIS-C3-RANGING-MIB file to load into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ARRIS-C3-RANGING-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 C3 CMTS (Cable Modem Termination System)
Monitoring Examples
An operator would poll ranging-process objects on the ARRIS C3 to track how many cable modems are failing initial or periodic ranging on a given upstream channel, a leading sign of upstream noise or plant impairment. A rising count of ranging timeouts or failures on one upstream port, correlated with modem flaps in the standard cable-modem MIBs, would point to a specific node or amplifier issue in the HFC plant. No sample object names were available for this module to cite directly.
What Can Be Monitored
- upstream ranging success/failure
- cable modem ranging status
- ranging process configuration
- upstream channel signal quality indicators
