Description: Manages syslog message configuration, severity filtering, and remote server destinations on Motorola BSR CMTS platforms.

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 RDN-SYSLOG-MIB?

RDN-SYSLOG-MIB is a Motorola-specific MIB that manages syslog message configuration on Motorola BSR CMTS platforms, including severity-level filtering and remote syslog server destination settings. It exposes configuration objects controlling how the CMTS forwards its internal log messages to external syslog collectors, rather than performance or environmental telemetry. Its monitoring value is primarily in verifying software-level logging health, confirming remote syslog server reachability, severity filter settings, and that critical system events are captured and forwarded for later fault analysis. It is a Motorola-proprietary enterprise MIB with no direct dependency on the standard SYSLOG-MIB, though it serves an analogous purpose. This MIB is typically used by cable operators to centralize log collection from Motorola BSR CMTS chassis into a network-wide syslog infrastructure for troubleshooting and compliance. Engineers can download the RDN-SYSLOG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RDN-SYSLOG-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

Motorola BSR CMTS (cable headend)

Monitoring Examples

No specific object names were provided in the sample_objects for this MIB, so a concrete polling scenario cannot be safely constructed; based on the description, it would likely expose objects for configuring remote syslog server addresses and minimum severity levels for forwarded messages. An operator would typically verify the configured remote syslog destination matches the intended log-collection server and that severity filtering is not silently dropping critical/error-level events, since misconfiguration here would manifest as missing log entries at the central collector during a CMTS fault.

How to Use in IPNetwork Monitor

Example using rdnSyslogSize OID:

Select a Motorola BSR CMTS cable headend (syslog severity filtering/remote server configuration) 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 rdnSyslogSize into the Find box to locate it in the OID tree, then select it and click OK. It reports the current size in bytes of the syslog file. 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 drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.
