What Is TN-CLEAR-MIB?

TN-CLEAR-MIB is a Nokia (formerly Alcatel-Lucent) module for the Nokia 7x50 service router/switch family that manages and provisions 'clear' operations - SNMP-triggered actions to reset counters, alarms, or operational state on the system. It exposes a table of clearable items with a name, parameters, an action trigger, the last time each was cleared, and the result/error text of the last clear operation, plus a couple of general-purpose scalar objects. Its monitoring value is centered on software/operational-action status: confirming whether a requested clear action (e.g. clearing alarm counters or statistics) succeeded, when it last ran, and any error encountered, rather than reporting hardware sensors. It is a Nokia 7x50-specific proprietary MIB, tightly coupled to that platform's internal object/alarm model rather than a standard IETF MIB. It is typically deployed on Nokia 7x50 carrier Ethernet/IP routers where operators or automation scripts trigger clear operations via SNMP and need to confirm they completed successfully. Engineers can download the TN-CLEAR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TN-CLEAR-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

Nokia 1830 PSS (Photonic Service Switch) optical transport platform

Monitoring Examples

An operator or automation script would set tnClearAction on a row identified by tnClearIndex/tnClearName in tnClearTable/tnClearEntry to trigger a clear operation, then poll tnClearResult and tnClearLastClearedTime to confirm it completed, checking tnClearErrorText if tnClearResult indicates failure. A tnClearResult showing an error alongside stale tnClearLastClearedTime timestamps would reveal that a scheduled clear job (e.g. clearing alarm counters) is failing silently. This lets operators verify that automated maintenance actions on the 7x50 are actually taking effect.

What Can Be Monitored

clear action trigger status
last cleared timestamp
clear operation result
clear operation error text
clearable item name/parameters

tnClearObjs	1.3.6.1.4.1.7483.6.1.2.13
tnClearTable	1.3.6.1.4.1.7483.6.1.2.13.1		not-accessible	The tnClearTable provides the Nokia 7x50 SR series EMS a way to execute the operational clear functions.
tnClearEntry	1.3.6.1.4.1.7483.6.1.2.13.1.1		not-accessible	Each row entry in the tnClearTable represents an operational clear function. Rows in this table are created by the agent when the system is initialized. They can be neither created nor destroyed by SNMP SET requests.
I32 tnClearIndex	1.3.6.1.4.1.7483.6.1.2.13.1.1.1	Integer32	not-accessible	The value of tnClearIndex specifies a unique clear function within an application group. The application group indexes, tnEventAppIndex, are given in the tnEventAppTable in the TN-LOG-MIB.
TNA tnClearName	1.3.6.1.4.1.7483.6.1.2.13.1.1.2	TNamedItem	read-only	The name of the application clear function associated with this row entry.
OCT tnClearParams	1.3.6.1.4.1.7483.6.1.2.13.1.1.3	OCTET STRING	read-write	The tnClearParams string is a sequence of parameter name value pairs to be used to determine the managed object to which to apply the application clear function associated with this row entry.
TMN tnClearAction	1.3.6.1.4.1.7483.6.1.2.13.1.1.4	TmnxActionType	read-write	Setting tnClearAction to 'doAction (1)' causes the application clear function associated with this row entry to be enacted.
TIM tnClearLastClearedTime	1.3.6.1.4.1.7483.6.1.2.13.1.1.5	TimeStamp	read-only	The tnClearLastClearedTime variable contains the sysUpTime value when tnClearAction was last set to 'doAction (1)' to run the application clear function associated with this row entry.
INT tnClearResult	1.3.6.1.4.1.7483.6.1.2.13.1.1.6	INTEGER	read-only	The result of the last attempt to enact the application clear function associated with this row entry.
OCT tnClearErrorText	1.3.6.1.4.1.7483.6.1.2.13.1.1.7	OCTET STRING	read-only	If the result of the last attempt to enact the application clear function associated with this row entry failed, tnClearResult is 'failure (2)', tnClearErrorText contains a text string to further explain the cause of the failure.
U32 tnClearScalar1	1.3.6.1.4.1.7483.6.1.2.13.101	Unsigned32	read-only	A dummy scalar that satisfies a SNMP get request quickly when there is no 11QPE24 card provisioned. Otherwise, it has to traverse the remaining 11QPE24 MIB to get to the next applicable item.
U32 tnClearScalar2	1.3.6.1.4.1.7483.6.1.2.13.102	Unsigned32	read-only	A dummy scalar that satisfies a SNMP get request quickly when there is no 11QPE24 card provisioned. Otherwise, it has to traverse the remaining 11QPE24 MIB to get to the next applicable item.
tnClearNotificationsPrefix	1.3.6.1.4.1.7483.6.1.3.13

NTF tnClear	1.3.6.1.4.1.7483.6.1.3.13.0.1			The tnClear notification is generated to report the results of the clear function that was run as a result of setting tnClearAction to 'doAction'.
