Description: Manages SNMP trap logging, trap destination configuration, and trap history on ARRIS/Cadant 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 CADANT-TRAP-LOG-MIB?

CADANT-TRAP-LOG-MIB is an ARRIS/Cadant enterprise MIB that controls and reports on proprietary SNMP trap generation and event logging on Cadant/ARRIS CMTS equipment. It exposes global settings for enabling proprietary logging, local log and history buffer sizes, syslog facility selection, per-modem trap inhibiting, and tables for controlling and overriding the reporting/severity state of individual events. Its role is squarely fault/event monitoring for the device's software, letting an operator see which event classes are enabled for trap generation or logging, adjust logging capacity, and confirm syslog integration is configured as expected. It complements, and can duplicate control of, the standard event/notification-log MIBs typical of SNMP agents. It is deployed on ARRIS/Cadant CMTS headend equipment as the central point for tuning trap and logging behavior across the chassis. Engineers can download the CADANT-TRAP-LOG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CADANT-TRAP-LOG-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 C4 CMTS cable modem termination system

Monitoring Examples

An operator would check cadLocalLogSize and cadLogHistorySize to confirm the CMTS retains enough event history for post-incident diagnosis, and cadSyslogFacility to verify events are being forwarded to the correct syslog facility. Reviewing cadEvControlTable/cadEvControlEntry for cadEvReporting per event, together with any active entries in cadEvOverrideTable (cadEvOvrdEvId, cadEvOvrdState), shows whether specific event types have been suppressed or overridden, which could explain missing alerts. Checking cadCmTrapInhibit helps confirm whether per-modem trap suppression is masking legitimate cable-modem fault notifications.

What Can Be Monitored

local log/history buffer size
syslog facility configuration
per-event trap reporting state
event override/suppression state
per-modem trap inhibit status

OIDs

OID symbolic	OID numeric	Type	Access	Description
cadTrapLogMib	1.3.6.1.4.1.4998.1.1.6.2			This MIB defines objects which are used to control and report on Cadant proprietary event notificaton (trap) and logging operation.
cadTrapLogGlobals	1.3.6.1.4.1.4998.1.1.6.2.1
T/F cadProprietaryLoggingEnabled	1.3.6.1.4.1.4998.1.1.6.2.1.1	TruthValue	read-write	If this value is set to true, then all Cadant proprietary log entries are enabled. Otherwise, the syslog logs will consist only of standard logs entries.
U32 cadLocalLogSize	1.3.6.1.4.1.4998.1.1.6.2.1.2	Unsigned32	read-write	The maximum size of the local log, in number of entries. The local log is only what is put into the docsDevEventTable.
U32 cadLogHistorySize	1.3.6.1.4.1.4998.1.1.6.2.1.3	Unsigned32	read-write	The maximum size of the log history, in number of entries. This log contains both Cadant prioprietary and DOCSIS notifications.
INT cadSyslogFacility	1.3.6.1.4.1.4998.1.1.6.2.1.4	INTEGER	read-write	The syslog logging facility.
BIT cadCmTrapInhibit	1.3.6.1.4.1.4998.1.1.6.2.1.5	Bits	read-write	Controls the generation of SNMP traps regarding to CM status change. A cleared bit indicates that a trap must be generated if a CM resets while in the corresponding state. If resetRanging(0) is clear, a CM reset while in the ranging state will generate a cmResetNotification trap. If resetProvisioning(1) is clear, a CM reset while in the rangingComplete or ipComplete states will generate a cmResetNotification trap. If resetRegistered(2) is clear, a CM reset while in the registrationComplete state will generate a cmResetNotification trap. If resetClear(3) is clear, a on-line CM from previous flap will generate a cmResetClearNotification trap. If registered(4) is clear, a registered CM will generate a cmRegistrationNotification trap.
cadEvControlTable	1.3.6.1.4.1.4998.1.1.6.2.2		not-accessible	This table allows control of the reporting of event classes. For each event priority, a combination of logging and reporting mechanisms may be chosen.
cadEvControlEntry	1.3.6.1.4.1.4998.1.1.6.2.2.1		not-accessible	Allows configuration of the reporting mechanisms for a particular event priority.
BIT cadEvReporting	1.3.6.1.4.1.4998.1.1.6.2.2.1.1	Bits	read-write	Currently, only the console destination is persistent in SNMP. Transient sessions, such as telnet, are not configurable via the MIB. Those are configurable only via CLI.
cadEvOverrideTable	1.3.6.1.4.1.4998.1.1.6.2.3		not-accessible	This table allows the event priority to be overridden. Each entry indicates an override condition for the given event.
cadEvOverrideEntry	1.3.6.1.4.1.4998.1.1.6.2.3.1		not-accessible	Allows configuration of the event priority overrides.
U32 cadEvOvrdEvId	1.3.6.1.4.1.4998.1.1.6.2.3.1.1	Unsigned32	read-only	Uniquely identifies the type of event that is reported by this entry.
INT cadEvOvrdState	1.3.6.1.4.1.4998.1.1.6.2.3.1.2	INTEGER	read-create	Indicates the current override state of the event. admit allows the event to be generated and inhibit prevents the event from being generated regardless of the priority is enabled for the event. Setting the priority allows the event to generated with the desired priority.
ROW cadEvOvrdRowStatus	1.3.6.1.4.1.4998.1.1.6.2.3.1.3	RowStatus	read-create	This variable indicates the status of the entry. Valid values for a set include createAndGo(4) and destroy(6).
INT cadEvOvrdPriority	1.3.6.1.4.1.4998.1.1.6.2.3.1.4	INTEGER	read-create	This field is only valid when the override state is set to priority and indicates the priority level that should be used when this notification is generated.
cadSyslogSvrTable	1.3.6.1.4.1.4998.1.1.6.2.4		not-accessible	This table stores syslog server information when there is more than one syslog server configured.
cadSyslogSvrEntry	1.3.6.1.4.1.4998.1.1.6.2.4.1		not-accessible	Syslog server information.
ADR cadSyslogSvrIpAddr	1.3.6.1.4.1.4998.1.1.6.2.4.1.1	InetAddressIPv4or6	not-accessible	IP address of the syslog server.
