Description: Manages generic network device chassis hardware including slots, modules, power supplies, and fan assemblies.

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 CHASSIS-MIB?

CHASSIS-MIB is a vendor-neutral, hardware-inventory style MIB module used to represent a network device's physical chassis, covering constructs such as slot occupancy, plug-in modules, power supplies, and fan assemblies. It exposes general categories of data around chassis composition and environmental subsystems rather than protocol or traffic statistics. Its central purpose is hardware health monitoring: administrators use it to check whether power supplies and fans are present and functioning, whether expansion modules are seated and recognized, and overall chassis integrity, which are leading indicators of impending hardware failure. Because it deals only with physical chassis structure, it is commonly used alongside the standard ENTITY-MIB and vendor-specific environmental MIBs that supply the numeric sensor readings. It is typically deployed on modular, multi-slot chassis-based network equipment such as core switches, routers, and telecom platforms where slot and power redundancy must be tracked. Engineers writing polling scripts for this module often start from a published CHASSIS-MIB OID list to map each slot, module, and power/fan object to its exact registration point in the tree.

IPNetwork Monitor allows you to monitor SNMP objects defined in 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.

Supported Devices

modular/chassis-based network switches and routers
vendor-neutral MIB not tied to one manufacturer

Monitoring Examples

An administrator would poll the chassis's slot and module table entries to confirm every physical module bay is populated with the expected card and to detect an unplugged or failed line card. Power-supply and fan status objects would be checked on a polling interval to catch a failed PSU or stalled fan before it causes overheating. Because CHASSIS-MIB was supplied with no sample object list, this description generalizes from its stated purpose rather than citing exact object names.

What Can Be Monitored

slot/module presence and status
power supply operational status
fan assembly status

By convention, this value is allocated within the SMI enterprises subtree(1.3.6.1.4.1), and provides an easy and unambiguous means for determining `what kind of box' is being managed. If this information is not present or unknown, its value should be set to chasTypeUnknown.
INT chasModuleAdminStatus	1.3.6.1.4.1.800.2.1.2.1.1.13	INTEGER	read-write	Provides desired (and actual) state of the given module. Notice that not all values may be supported by a specified physical module. In this case an SNMP error returned when a set is attempted. All modules (even empty slots) are in an unknown(1) state when the chassis first powers up. The invalid state is for non-existant modules, and hence is never seen. Neither of the unknown(1) or invalid(2) status values can be written. A physical module can be activated by writing a value of enable(3). A physical module may be de-activated by writing a value of disable(4). In a disabled state, the module is present in the chassis, but is benign. A disabled module is availible for subsequent activation. Writing a value of reset(5), disables the module AND initiates a reset sequence. Writing a value of load(6), disables the module AND initiates a software load sequence. Writing a value of test(7), disables the module AND initiates selftest within the module.

INT chasModuleHwRevision	1.3.6.1.4.1.800.2.1.2.1.1.6	INTEGER	read-only	The current revision of this module's hardware.
INT chasModuleLedStatus	1.3.6.1.4.1.800.2.1.2.1.1.15	INTEGER	read-only	The LED state for this module. The exact definition of the values are implimentation dependent. For example, a power supply module may not have any LEDs present, while a network interface element might have 28 LEDs and a Controller might have 6 LEDs. NOTE: due to European regulation, the LEDs will NEVER be illuminated RED! They in fact will be either green OR amber. This will be reflected in the MIB as either GRN=1/RED=0 or GRN=1/RED=1. Of course, if both are off then the LED is not illuminated. The current bit definitions for the defined modules are: mpm 0 - OK1 RED (0 off, 1 on) 1 - OK2 RED (0 off, 1 on) 2 - PS1 RED (0 off, 1 on) 3 - PS2 RED (0 off, 1 on) 4 - OK1 GRN (0 off, 1 on) 5 - OK2 GRN (0 off, 1 on) 6 -

OCT chasModuleLedStatusExtend	1.3.6.1.4.1.800.2.1.2.1.1.18	OCTET STRING	read-only	A octet string containing module led information
STR chasModuleMfgDate	1.3.6.1.4.1.800.2.1.2.1.1.9	DisplayString	read-only	The manufacturing date for this module. This data is retrieved from the module non-volitile memory.
INT chasModuleOperStatus	1.3.6.1.4.1.800.2.1.2.1.1.14	INTEGER	read-only	Provides operational state of the given module. The exact definition of the values is implementation specific. A value of unknown(1) implies some undetermined state, possibly as a result of a module failing the low-level selftest. A value of invalid(2) may mean that the module exists but the chassis manager has no direct control over it. A value of operational(3) implies that the entity is running with no errors or warnings. A value of disabled(4) reflects the response to the chasModuleAdminStatus of disable(4). A value of resetInProgress(5) also reflects the equivalent AdminStatus reset(5). Note that the states warning(8), nonFatalError(9), and fatalError(10) reflect conditions detected during operation. The module may or may not be fuctional at this point. For example a module's value of AdminStatus is disable(4), the OperStatus will reflect that. The AdminStatus is set to enable(3), the OperStatus might then change to testing(7) then change to operational(3).
STR chasModulePartNum	1.3.6.1.4.1.800.2.1.2.1.1.4	DisplayString	read-only	The part number of ths module.

XYL chasModuleSubUnit	1.3.6.1.4.1.800.2.1.2.1.1.2	XylanModuleSubunit	read-only	The sub-unit number within module in slot 'n'. For each non-empty slot there will exist a module entry with a chasModuleSubUnit value of base. If the chasModuleType of that chasModuleEntry is hsm, then there may be additional chasModuleEntrys with the same chasModuleSlot value but with chasModuleSubUnit values of hsm1, hsm2 or csm3. These are HSM or CSM-U sub-modules. An HSM module can have up to 2 daughter cards on it. The first position would be denoted by hsm1(2) and the second position is hsm2(3). A CSM-U module can have up to 3 daughter cards on it.The first position would be denoted by hsm1(2) and the second position is hsm2(3) and the third postion is csm3(4). The general implication of this field is: each occupied slot will have an entry field will be base(1), and may if the module supports daughter cards have entries for which if this field is hsm1(2), hsm2(3) or cms3(4), corrosponding to an installed daughter card on the HSM or CMS-U in the specified chasModuleSlot. (and the card type will be listed in chasModuleType).

CTR chasModuleVbusTxDiscards	1.3.6.1.4.1.800.2.1.2.1.1.16	Counter	read-only	The current count of transmit VBUS buffer overruns.
INT chasNewDupMacSupport	1.3.6.1.4.1.800.2.1.1.11	INTEGER	read-write	This variable allows the user to cause duplicate MAC addresses to age out concurrently. If set to zero, it is ignored and the aging timer for each group where the address was learned will be used. Values 1 through 9 are not valid. If set to a value between 10 and 1000000, it will be used instead of the group aging timers. Units are seconds.
CTR chasNoOfResets	1.3.6.1.4.1.800.2.1.1.6	Counter	read-only	This object is a count of the number of times this this station has been reset since a cold-start.
