Description: DVB/DAVIC MIB for EuroModem-compliant INA cable interface management on DVB-RC broadband cable access devices

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 DVB-CABLE-INA-IF-MIB?

DVB-CABLE-INA-IF-MIB is a standard MIB from the DVB/DAVIC Interoperability Consortium Technical Working Group, defining interface objects for INAs (Interactive Network Adapters) conforming to the EuroModem specification (assumes MIB-II/RFC 1213 support). Its MAC table, keyed by interface, records device capabilities/extended capabilities, MAC capabilities/extended capabilities, protocol support, a set of numbered plus D/E/F contention timeouts, rapid-sign-on enable, response-collision time window, address-filter use/position-mask/comparison-value, grant-protocol timeout, idle interval/invalid count, and contention-message parameters (N, max length). As a configuration/protocol-status MIB it lets an administrator confirm a DVB cable INA's MAC-layer contention and addressing parameters conform to the EuroModem specification. It is deployed on DVB/DAVIC-compliant cable Interactive Network Adapters (EuroModem). Engineers implementing or auditing this functionality typically reference the DVB-CABLE-INA-IF-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in DVB-CABLE-INA-IF-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

  • DVB/DAVIC-compliant cable Interactive Network Adapters (EuroModem)

Monitoring Examples

An administrator checks dvbInaIfMacProtocolSupport and dvbInaIfMacRapidSignOnEnable to confirm a cable INA's EuroModem MAC-layer configuration conforms to the DVB/DAVIC specification.

What Can Be Monitored

  • MAC-layer contention/addressing configuration

How to Use in IPNetwork Monitor

Example using dvbInaIfMacUnknownNiuError OID:

Select a DVB/DAVIC EuroModem cable Interactive Network Adapter (vendor-neutral standard) 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 dvbInaIfMacUnknownNiuError 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. This value is incremented if a message is received from a unknown NIU, except if it is a SignOn_Response Message. 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, 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.
