What Is WWP-LEOS-TABLE-CHG-NOTIF-MIB?

WWP-LEOS-TABLE-CHG-NOTIF-MIB is a Ciena LEOS (formerly World Wide Packets) proprietary MIB that defines SNMP notifications for configuration table change events, maintaining a table that tracks which (table, EMS IP) pairs should trigger a notification when the referenced table is modified. It exposes configuration data describing which tables are being watched and which Element Management System (EMS) targets should be notified of a change, plus the associated change-event notifications themselves. Its monitoring value is in configuration-drift and change-tracking awareness rather than hardware/software runtime health — it lets an EMS learn in near real time that a specific configuration table on the device has been altered, which is useful for keeping a management system's cached configuration in sync. It depends on the standard SNMP notification (trap/inform) mechanism to deliver the change events. It is deployed on Ciena LEOS Metro Ethernet devices managed by an EMS that needs proactive notification of configuration changes rather than polling. Network engineers evaluating or troubleshooting this functionality can download the WWP-LEOS-TABLE-CHG-NOTIF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWP-LEOS-TABLE-CHG-NOTIF-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; based on the description, the relevant object is a table mapping (table identifier, EMS IP address) pairs used to determine which management stations receive a change notification for a given table. An admin or EMS integrator would poll this mapping table to confirm the correct EMS IP is registered for each configuration table of interest, and a missing registration would explain why the EMS failed to receive an expected change notification after a configuration update.

OIDs

OID symbolic	OID numeric	Type	Access	Description
wwpLeosTableChgNotifMIB	1.3.6.1.4.1.6141.2.60.9			This MIB module is used to maintain the table of (Table, Ems IP)
wwpLeosTableChgNotifMIBObjects	1.3.6.1.4.1.6141.2.60.9.1
INT wwpLeosTableTrapNotifTimer	1.3.6.1.4.1.6141.2.60.9.1.1	INTEGER	read-write	Setting this value will set the trap timer. Device will send the trap notification after every wwpLeosTableTrapNotifTimer seconds if any of the table changes.
INT wwpLeosListenerRefreshTimer	1.3.6.1.4.1.6141.2.60.9.1.2	INTEGER	read-write	Setting this value will set the listener refresh timer. Device will send the trap notification 'wwpLeosTableRefreshTrap' after every 'wwpLeosListenerRefreshTimer' seconds if count value associated with 'wwpLeosListenerEntry' becomes 20 or 10 or 5. Device will delete entry from wwpLeosListenerEntry once count = 0. Minimum value is 30 sec and maximum = 1000 seconds.
wwpLeosTableChgNotifTable	1.3.6.1.4.1.6141.2.60.9.1.4		not-accessible	Table of Ems.
wwpLeosTableChgNotifEntry	1.3.6.1.4.1.6141.2.60.9.1.4.1		not-accessible	Ems Entry in the ems Port Table.
INT wwpLeosTableChgNotifIndex	1.3.6.1.4.1.6141.2.60.9.1.4.1.1	INTEGER	read-only	This is the index used for this table.
OID wwpLeosTableChgNotifOid	1.3.6.1.4.1.6141.2.60.9.1.4.1.2	OBJECT IDENTIFIER	read-only	This is the OID of the table for which device will send trap if anything changed in this table.
C32 wwpLeosTableChgNotifNumChanges	1.3.6.1.4.1.6141.2.60.9.1.4.1.3	Counter32	read-only	This variables returns the counter value which keeps track of how many times wwpLeosTableChgNotifOid has changed. This counter is 32 bit counter and will never reset, except if device is rebooted.
wwpLeosListenerTable	1.3.6.1.4.1.6141.2.60.9.1.5		not-accessible	Table of EMS/NMS Ip's. This table uses Multiple Set operation to create entry in the table.
wwpLeosListenerEntry	1.3.6.1.4.1.6141.2.60.9.1.5.1		not-accessible	Entry of each EMS/NMS who is interested to receive table change notification.
INT wwpLeosListenerIndex	1.3.6.1.4.1.6141.2.60.9.1.5.1.1	INTEGER	read-only	Specifies the unique index in the wwpLeosListenerTable.
STR wwpLeosListenerAddr	1.3.6.1.4.1.6141.2.60.9.1.5.1.2	DisplayString	read-create	This is the host name or ip address of the EMS/NMS.
IP wwpLeosListenerResolvedIp	1.3.6.1.4.1.6141.2.60.9.1.5.1.3	IpAddress	read-only	This shows the resolved IP address of the host name specified in wwpLeosListenerAddr. If wwpLeosListenerAddr is set to IpV4 type then wwpLeosListenerResolvedIp is equal to wwpLeosListenerAddr. If wwpLeosListenerAddr is set to dns type then wwpLeosListenerResolvedIp is equal to 0 if it is unresolved or is equal to resolved IP address.
ROW wwpLeosListenerStatus	1.3.6.1.4.1.6141.2.60.9.1.5.1.4	RowStatus	read-create	Used to manage the creation and deletion of the conceptual rows in this table. To create a row in this table, a manager must set this object to 'createAndGo'. Setting this object to 'active' if it is already active will result in refreshing this entry. Setting this object to 'create and go' if this entry is already active will result in refreshing this entry. This table uses Multiple Set operation to create entry in the table. wwpLeosListenerAddr and wwpLeosListenerStatus and index are mandatory objects that need to be set when creating entry. While deleting entry ony index needs to be specified.
wwpLeosTableChgNotif	1.3.6.1.4.1.6141.2.60.9.1.7
