What Is CTRON-CHASSIS-MIB?

CTRON-CHASSIS-MIB is a Cabletron (Enterasys) enterprise MIB that models the physical hardware inventory of a Cabletron modular chassis, including slot assignments, installed module types, and overall chassis health. It exposes hardware-inventory data — what type of module occupies each slot — plus chassis-level or per-slot health/status indicators. Its central purpose is monitoring hardware status: it is the primary way to detect that a module has been removed, has failed, or is reporting a fault condition within the chassis, similar in spirit to an entPhysicalTable-style inventory but with Cabletron-specific chassis semantics. It is commonly used together with the standard ENTITY-MIB and with Cabletron's own environment MIB (temperature/power/fan) to build a complete physical-health picture of the device. It is deployed on modular, slot-based Cabletron/Enterasys switches and hubs that support hot-swappable line modules, and administrators maintaining older Cabletron gear can still find a CTRON-CHASSIS-MIB download to load into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-CHASSIS-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.

Monitoring Examples

No sample object names were supplied for this module in the source data, so a table-level walkthrough can't be grounded in real identifiers. In practice, an administrator would poll per-slot module-type and module-status objects to detect an unexpected "empty" or "fault" state where a module was previously reporting "ok," signaling a card failure or removal. Because specific object names weren't available, this remains a conceptual example rather than an object-referenced one.

What Can Be Monitored

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
ctChas	1.3.6.1.4.1.52.4.3.1.1
INT ctChasFNB	1.3.6.1.4.1.52.4.3.1.1.1	INTEGER	read-only	Denotes the presence or absence of the FNB.
INT ctChasAlarmEna	1.3.6.1.4.1.52.4.3.1.1.2	INTEGER	read-write	Allow an audible alarm to be either enabled or dis- abled. Setting this object to disable(1) will prevent an audible alarm from being heard and will also stop the sound from a current audible alarm. Setting this object to enable(2) will allow an audible alarm to be heard and will also enable the sound from a current audible alarm, if it has previously been disabled. This object will read with the current setting.
INT chassisAlarmState	1.3.6.1.4.1.52.4.3.1.1.3	INTEGER	read-only	Denotes the current condition of the power supply fault detection circuit. This object will read with the value of chassisNoFaultCondition(1) when the chassis is currently operating with no power faults detected. This object will read with the value of chassisFaultCondition(2) when the chassis is currently in a power fault condition.
ctEnviron	1.3.6.1.4.1.52.4.3.1.2
ctChasPowerTable	1.3.6.1.4.1.52.4.3.1.2.1		not-accessible	A list of power supply entries.
ctChasPowerEntry	1.3.6.1.4.1.52.4.3.1.2.1.1		not-accessible	An entry in the powerTable providing objects for a power supply.
INT ctChasPowerSupplyNum	1.3.6.1.4.1.52.4.3.1.2.1.1.1	INTEGER	read-only	Denotes the power supply.
INT ctChasPowerSupplyState	1.3.6.1.4.1.52.4.3.1.2.1.1.2	INTEGER	read-only	Denotes the power supply's state.
INT ctChasPowerSupplyType	1.3.6.1.4.1.52.4.3.1.2.1.1.3	INTEGER	read-only	Denotes the power supply type.
INT ctChasPowerSupplyRedundancy	1.3.6.1.4.1.52.4.3.1.2.1.1.4	INTEGER	read-only	Denotes whether or not the power supply is redundant.
ctFanModule	1.3.6.1.4.1.52.4.3.1.3
ctChasFanModuleTable	1.3.6.1.4.1.52.4.3.1.3.1		not-accessible	A list of fan module entries.
ctChasFanModuleEntry	1.3.6.1.4.1.52.4.3.1.3.1.1		not-accessible	An entry in the fan module Table providing objects for a fan module.
INT ctChasFanModuleNum	1.3.6.1.4.1.52.4.3.1.3.1.1.1	INTEGER	read-only	Denotes the Fan module that may have failed.
INT ctChasFanModuleState	1.3.6.1.4.1.52.4.3.1.3.1.1.2	INTEGER	read-only	Denotes the fan modules state.
