Description: Enterasys Networks MIB for committing persistent SNMP configuration data to non-volatile storage on demand.

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 ENTERASYS-SNMP-PERSISTENCE-MIB?

This Enterasys Networks enterprise MIB gives management applications a way to explicitly commit in-memory SNMP configuration changes to non-volatile (persistent) storage on the device, rather than relying on automatic periodic saves. It exposes a persistence mode setting, a save trigger object, and status/timestamp/error objects reflecting the outcome of the last save operation. Its monitoring value is squarely operational/software status: polling etsysSnmpPersistenceStatus and etsysSnmpPersistenceStatusTime after triggering etsysSnmpPersistenceSave confirms whether the configuration was actually written to flash, while etsysSnmpPersistenceError and etsysSnmpPersistenceErrorTime reveal a failed save (e.g., due to storage exhaustion), critical to avoid silent configuration loss on reboot. It is a self-contained enterprise MIB with no dependency on external standard MIBs. It is deployed on Enterasys/Extreme switches and routers as part of automated configuration-management workflows. Engineers can download the ENTERASYS-SNMP-PERSISTENCE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-SNMP-PERSISTENCE-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

Enterasys/Extreme Networks switch or router

Monitoring Examples

A configuration-management tool would set etsysSnmpPersistenceSave to trigger a commit, then poll etsysSnmpPersistenceStatus and etsysSnmpPersistenceStatusTime until it reports success, confirming the running configuration was saved to non-volatile storage before a planned reboot. If etsysSnmpPersistenceError is non-zero, the tool would alert that the last save attempt failed, preventing an unnoticed loss of configuration changes.

OIDs

OID symbolic	OID numeric	Type	Access	Description
etsysSnmpPersistenceMIB	1.3.6.1.4.1.5624.1.2.24			This MIB modules provides objects that allow management applications to commit persistent SNMP configuration information to persistent storage.
etsysSnmpPersistenceObjects	1.3.6.1.4.1.5624.1.2.24.1
INT etsysSnmpPersistenceMode	1.3.6.1.4.1.5624.1.2.24.1.1	INTEGER	read-write	Setting this object to snmpNormalSave(1) will cause this device to exhibit what could be considered normal SNMP behavior, that is each SNMP set of a persistent object will be saved to persistent storage as part of the set operation. Setting this object to pushButtonSave(2) will cause SNMP sets of persistent objects to be buffered in volatile memory until the configuration is explicitly saved to persistent memory, either through the CLI or by setting the etsysSnmpPersistenceWrite object to save(2). Setting this object to timeDelayedSave(3) will cause SNMP sets of persistent objects to be buffered in volatile memory until certain implementation dependent time conditions are met. Once these conditions are met the configuration is saved to persistent memory. Setting this object to a mode that is not supported on that particular implementation leads to an inconsistent value error. On an SNMP get operation this object will return the current persistent storage mode of operation.
INT etsysSnmpPersistenceSave	1.3.6.1.4.1.5624.1.2.24.1.2	INTEGER	read-write	Setting this object to save(2) will cause the current configuration that is stored in volatile memory to be written to persistent memory and become the start-up configuration. This will also cause any configuration information that is part of another management interface's active configuration to become part of the start-up configuration. Any configuration changes made through SNMP will become part of the start-up configuration if and when another management interface saves the current configuration to persistent storage. Setting this object to save(2) while the value of the etsysSnmpPersistenceMode object is NOT pushButtonSave(2) MAY lead to an inconsistent value error. Setting this object to save(2) while the value of the etsysSnmpPersistenceStatus object is savingChanges(3) leads to an inconsistent value error. Setting this object to nop(1) always succeeds and has no effect. On an SNMP get operation this object will return nop(1). Management applications are advised to make use of the snmpSetSerialNo object defined in the SNMPv2-MIB to coordinate their use of this object.
INT etsysSnmpPersistenceStatus	1.3.6.1.4.1.5624.1.2.24.1.3	INTEGER	read-only	This object reports the current status of the persistent storage system when the etsysSnmpPersistenceMode object is NOT set to snmpNormalSave(1). other - The value returned after initialization and before any configuration changes are made when the etsysSnmpPersistenceMode object is NOT set to snmpNormalSave(1). The value returned in all cases when the etsysSnmpPersistenceMode object is set to snmpNormalSave(1). unsavedChanges - The value returned when there are existing configuration changes that have not been saved to persistent storage. savingChanges - The value returned during the process of writing the current configuration to persistent storage. saveSucceeded - The value returned after the process of writing the current configuration to persistent storage has succeeded. saveFailed - The value returned after the process of writing the current configuration to persistent storage has failed. This status will reflect operations initiated through SNMP as well as all other supported management interfaces.
TIK etsysSnmpPersistenceStatusTime	1.3.6.1.4.1.5624.1.2.24.1.4	TimeTicks	read-only	The value of sysUpTime when etsysSnmpPersistenceStatus was last updated. If etsysSnmpPersistenceStatus has not been updated since initialization the value zero is returned.
STR etsysSnmpPersistenceError	1.3.6.1.4.1.5624.1.2.24.1.5	SnmpAdminString	read-only	This object contains a descriptive error message if the last attempt to write to persistent storage has failed.
DAT etsysSnmpPersistenceErrorTime	1.3.6.1.4.1.5624.1.2.24.1.6	DateAndTime	read-only	The data and time when the etsysSnmpPersistenceError was last updated. If etsysSnmpPersistenceError has not been updated since initialization the value '0000000000000000'H is returned.
etsysSnmpPersistenceConformance	1.3.6.1.4.1.5624.1.2.24.2
etsysSnmpPersistenceGroups	1.3.6.1.4.1.5624.1.2.24.2.1
etsysSnmpPersistenceGroup	1.3.6.1.4.1.5624.1.2.24.2.1.1			A collection of objects providing support for delayed persistence of otherwise persistent SNMP objects.
etsysSnmpPersistenceCompliances	1.3.6.1.4.1.5624.1.2.24.2.2
etsysSnmpPersistenceCompliance	1.3.6.1.4.1.5624.1.2.24.2.2.1			The compliance statement for devices that support delayed persistence of otherwise persistent SNMP objects.
