What Is CISCO-MODULE-AUTO-SHUTDOWN-MIB?

CISCO-MODULE-AUTO-SHUTDOWN-MIB is a Cisco Systems, Inc. proprietary MIB configuring the module auto-shutdown feature, which shuts down a chassis module that resets too frequently (indicating a hardware fault) to prevent repeated disruptive reboots. Its objects cover a reset-frequency/period threshold, a MIB-wide and per-module system-action notification enable, and a module table (enable, reset count, last reset reason/time, system action, action reason, auto-shutdown flag, action notification). As a configuration/notification MIB it lets an administrator confirm which module was auto-shutdown and why after repeated faults on a Cisco chassis. It is deployed on Cisco Systems modular chassis platforms. Engineers can download the CISCO-MODULE-AUTO-SHUTDOWN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MODULE-AUTO-SHUTDOWN-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

Cisco Systems modular chassis platforms

Monitoring Examples

An administrator checks cmasModuleLastResetReason and cmasModuleAutoShutdown to confirm why a faulty module was auto-shutdown on a Cisco chassis.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using cmasModuleNumResets OID:

Select a Cisco modular chassis platform 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 cmasModuleNumResets 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 indicates the number of system initiated module resets that have occurred. 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 Gauge32-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.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoModuleAutoShutdownMIB	1.3.6.1.4.1.9.9.386			The CISCO-MODULE-AUTO-SHUTDOWN-MIB is used to configure the module automatic shutdown feature. Modules will be reset by the system when they become faulty. The module auto shutdown feature will shutdown such faulty modules when the resets occur too often. Once the modules are shutdown by this feature, they will stay shutdown until the administrator manually brings them back up. This will prevent the system from constantly resetting the faulty modules. This MIB module also covers the system initiated action occuring on a module.
cmasMIBNotifs	1.3.6.1.4.1.9.9.386.0
NTF cmasModuleAutoShutdown	1.3.6.1.4.1.9.9.386.0.1			This notification is generated when the module auto shutdown feature shuts down a module.
NTF cmasModuleSysActionNotif	1.3.6.1.4.1.9.9.386.0.2			This notification is generated when a system initiated action occurs on a module.
cmasMIBObjects	1.3.6.1.4.1.9.9.386.1
cmasGlobal	1.3.6.1.4.1.9.9.386.1.1
U32 cmasFrequency	1.3.6.1.4.1.9.9.386.1.1.1	Unsigned32	read-write	This indicates the threshold of the number of times the system can reset a faulty module, within the period specified by 'cmasPeriod'. Once the number of these system initiated resets exceeds this threshold, the module auto shutdown feature will shut down the module.
U32 cmasPeriod	1.3.6.1.4.1.9.9.386.1.1.2	Unsigned32	read-write	This indicates the period of time over which the number of system initiated module resets is monitored. In order for the module to be automatically shutdown, the number of times the system must reset the module has to exceed cmasFreqency times, in a span of cmasPeriod.
cmasNotifObjects	1.3.6.1.4.1.9.9.386.1.2
T/F cmasMIBEnableNotification	1.3.6.1.4.1.9.9.386.1.2.1	TruthValue	read-write	This object indicates whether the system produces the cmasModuleAutoShutdown notification.
T/F cmasModuleSysActionNotifEnable	1.3.6.1.4.1.9.9.386.1.2.2	TruthValue	read-write	This object indicates whether the system produces the cmasModuleSysActionNotif notification.
cmasModule	1.3.6.1.4.1.9.9.386.1.3
cmasModuleTable	1.3.6.1.4.1.9.9.386.1.3.1		not-accessible	This table contains information regarding the module auto shutdown feature.
cmasModuleEntry	1.3.6.1.4.1.9.9.386.1.3.1.1		not-accessible	This entry contains information about the module auto shutdown feature. Each entry represents whether the feature is enabled, the number of resets, the last reset reason and the last reset time. Each entry is applicable for the modules capable of this feature and are identified by 'entPhysicalIndex' with entPhysicalClass value 'module'.
T/F cmasModuleEnable	1.3.6.1.4.1.9.9.386.1.3.1.1.1	TruthValue	read-write	This object enables or disables the auto shutdown feature on a module. When the object is true(1), auto shutdown is enabled for that module. The feature will start monitoring system initiated module resets, and initiate a shutdown operation on the module if the number of resets, cmasModuleNumResets, exceeds the cmasFrequency within the previous cmasPeriod of time. When the object is false(2), auto shutdown is disabled for that module.
G32 cmasModuleNumResetsEx	1.3.6.1.4.1.9.9.386.1.3.1.1.2	Gauge32	read-only	This indicates the number of system initiated module resets that have occurred. This does not include user initiated module resets.
STR cmasModuleLastResetReason	1.3.6.1.4.1.9.9.386.1.3.1.1.3	SnmpAdminString	read-only	This object identifies the reason for the last module reset initiated by the system. This object will contain a zero-length string if no such resets have occurred.
DAT cmasModuleLastResetTime	1.3.6.1.4.1.9.9.386.1.3.1.1.4	DateAndTime	read-only	This object corresponds to the date and time when the last system initiated module reset occurred. This object will contain 0-1-1,00:00:00:0 if no system initiated resets have occurred.
cmasModuleSysActionObjects	1.3.6.1.4.1.9.9.386.1.4
CIS cmasModuleSysAction	1.3.6.1.4.1.9.9.386.1.4.1	CiscoModuleAutoShutSysAction	accessible-for-notify	This object identifies the system initiated action which is applied to a module.
STR cmasModuleSysActionReason	1.3.6.1.4.1.9.9.386.1.4.2	SnmpAdminString	accessible-for-notify	This object identifies the reason of system initiated action which is applied to a module.
