Cause	The tmnxNatDetMapOperStateChanged notification is sent when the value of the object tmnxNatDetMapOperState changes. The cause is explained in the tmnxNatNotifyDescription.
Effect	N/A
Recovery	N/A

tmnxNatDetPlcyChanged

Table 2. tmnxNatDetPlcyChanged properties
Property name	Value
Application name	NAT
Event ID	2022
Event name	tmnxNatDetPlcyChanged
SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.22
Default severity	minor
Message format string	The Deterministic NAT map has changed.
Cause	Such a change may be caused by a modification of the tmnxNatDetPlcyTable or the tmnxNatDetMapTable.
Effect	Traffic flows of one or more given subscribers, subject to NAT, may be assigned a different outside IP address and/or outside port.
Recovery	Managers that rely on the offline representation of the Deterministic NAT map should get an updated copy.

tmnxNatFwd2EntryAdded

Table 4. tmnxNatFwd2EntryAdded properties
Property name	Value
Application name	NAT
Event ID	2031
Event name	tmnxNatFwd2EntryAdded
SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.31
Default severity	minor
Message format string	{$tmnxNatNotifyPlSeqNum$} $tmnxNatNotifyTruthValue$ $tmnxNatFwd2OutAddr$ [$tmnxNatFwd2OutPort$] -- subscriber type <type> {<inside router> <inside IP> [AFTR $tmnxNatFwd2LsnAftrAddr$\| <subscriber id> } <inside port> <protocol> from $tmnxNatFwd2Origin$
Cause	The tmnxNatFwd2EntryAdded notification is sent when a row is added to or removed from the tmnxNatFwd2Table; a row can be added to the table either by operations on the tmnxNatFwdAction object group or by means of the PCP protocol. When the row is added, the value of the object tmnxNatNotifyTruthValue is 'true'; when the row is removed, it is 'false'.
Effect	The specified NAT subscriber can start receiving inbound traffic flows.
Recovery	No recovery required; this notification is the result of an operator or protocol action.

tmnxNatFwd2OperStateChanged

Table 5. tmnxNatFwd2OperStateChanged properties
Property name	Value
Application name	NAT
Event ID	2034
Event name	tmnxNatFwd2OperStateChanged
SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.34
Default severity	warning
Message format string	The state of forwarding entry subscriber type <type> {<inside router> <inside IP> subscriber $tmnxNatFwd2L2awSubIdent$ } IP protocol $tmnxNatFwd2Protocol$ inside port $tmnxNatFwd2Port$ policy $tmnxNatFwd2NatPolicy$ changed to $tmnxNatFwd2OperState$
Cause	The tmnxNatFwd2OperStateChanged notification is sent when the value of the object tmnxNatFwd2OperState changes. This is related to the state of the ISA MDA where the forwarding entry is located, or the availability of resources on that MDA. In the case of Layer-2-Aware NAT subscribers, the tmnxNatFwd2OperState is 'down' while the subscriber is not instantiated. This would typically be a transient situation.
Effect	The corresponding inward bound packets are dropped while the operational status is 'down'.
Recovery	If the ISA MDA reboots successfully, or another ISA MDA takes over, no recovery is required. If more resources become available on the ISA MDA, no recovery is required.

tmnxNatInAddrPrefixBlksFree

Application name	NAT
Event ID	2016
Event name	tmnxNatPlAddrFree
SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.16
Default severity	minor
Message format string	TODO
Cause	The tmnxNatPlAddrFree notification is sent when a range of outside IP addresses becomes free at once. The range starts at address tmnxNatNotifyOutsideAddr and ends with address tmnxNatNotifyOutsideEndAddr. It replaces a number of tmnxNatPlBlockAllocationL2Aw or tmnxNatPlBlockAllocationLsn notifications; the allocated port blocks associated with each IP address in the indicated range are released. The reason why this address range is released, is described in the tmnxNatNotifyDescription. If the value of tmnxNatNotifyInsideVRtrID is not equal to zero, it means that only the port blocks associated with hosts in that particular virtual router instance are released; if the value of tmnxNatNotifyInsideVRtrID is equal to zero, it means that all the port blocks are released.
Effect	N/A
Recovery	N/A

tmnxNatPlBlockAllocationL2Aw

Table 24. tmnxNatPlBlockAllocationL2Aw properties
Property name	Value
Application name	NAT
Event ID	2013

SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.12
Default severity	minor
Message format string	TODO
Cause	The tmnxNatPlBlockAllocationLsn notification is sent when an outside IP address and a range of ports is allocated to a NAT subscriber associated with a Large Scale NAT (LSN) pool, and when this allocation expires. The allocated block is within the scope of the outside virtual router instance tmnxNatNotifyOutsideVRtrID and the outside IP address tmnxNatNotifyOutsideAddr; it starts with port tmnxNatNotifyPort and ends with port tmnxNatNotifyPort2. The NAT subscriber is identified with its subscriber ID tmnxNatNotifyLsnSubId. To further facilitate the identification of the NAT subscriber, its type tmnxNatNotifySubscriberType, inside IP address tmnxNatNotifyInsideAddr and inside virtual router instance tmnxNatNotifyInsideVRtrID are provided. The values of tmnxNatNotifyMdaChassisIndex, tmnxNatNotifyMdaCardSlotNum and tmnxNatNotifyMdaSlotNum identify the ISA MDA where this block is processed. The value of tmnxNatNotifyNumber is the numerical identifier of the NAT policy used for this allocation; it can be used for correlation of notifications, especially with the tmnxNatPlAddrFree summary event, that may indicate this number in the tmnxNatNotifyDescription object. When the block allocation is made, the value of the object tmnxNatNotifyTruthValue is 'true'; when the block allocation expires, it is 'false'.

SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.17
Default severity	warning
Message format string	TODO
Cause	The tmnxNatPlLsnRedActiveChanged notification is sent when the value of the object tmnxNatPlLsnRedActive changes. The cause is explained in the tmnxNatNotifyDescription.
Effect	While the value of the object tmnxNatPlLsnRedActive is equal to 'false', ... - this system is not performing Large Scale NAT in the realm of the virtual router instance associated with this pool; the Large Scale NAT is supposed to be performed by its redundant peer. - the route specified with tmnxNatVrtrInRedSteerRt is not advertised in the realm of any inside virtual router instance associated with this pool; - NAT traffic matching a filter with TFilterAction equal to 'nat' is redirected to the address specified with tmnxNatVrtrInRedPeerAddr or dropped if tmnxNatVrtrInRedPeerAddr is not configured; - the pool ranges associated with this pool are withdrawn from the outside virtual router instance associated with this pool; - the route specified with tmnxNatPlLsnRedExpPrefix is not exported in the realm of the outside virtual router instance associated with this pool.
Recovery	If this system is supposed to assume the role of a standby in the realm of the virtual router instance associated with this pool, no recovery is needed. Otherwise, the recovery action will depend on the actual cause as specified in the tmnxNatNotifyDescription.

Table 31. tmnxNatVrtrOutDnatOnlyRoutesHigh properties
Property name	Value
Application name	NAT
Event ID	2035
Event name	tmnxNatVrtrOutDnatOnlyRoutesHigh
SNMP notification prefix and OID	TIMETRA-NAT-MIB.tmnxNatNotifications.35
Default severity	warning
Message format string	The DNAT-only routes high water status changed to $tmnxNatNotifyTruthValue$: $tmnxNatVrtrOutDnatOnlyRoutes$/ $tmnxNatVrtrOutDnatOnlyRouteLimit$.
Cause	The tmnxNatVrtrOutDnatOnlyRoutesHigh notification is sent with the value 'true' for tmnxNatNotifyTruthValue when the actual value of the object tmnxNatVrtrOutDnatOnlyRoutes approaches the configured value of tmnxNatVrtrOutDnatOnlyRouteLimit for a given virtual router instance. The same notification is sent with 'false' for tmnxNatNotifyTruthValue when the value of tmnxNatVrtrOutDnatOnlyRoutes goes below the threshold value again.
Effect	While the value of tmnxNatVrtrOutDnatOnlyRoutes is between the threshold value and the tmnxNatVrtrOutDnatOnlyRouteLimit limit, there is no effect. When an attempt is made to change the configuration within the virtual router instance such that the actual value of tmnxNatVrtrOutDnatOnlyRoutes would exceed the tmnxNatVrtrOutDnatOnlyRouteLimit limit, the system would refuse that attempt.
Recovery	Within the associated NAT inside virtual router instance, - reduce the number of prefixes (in the tmnxNatPrefixTable), - reduce the value of tmnxNatVrtrInMaxDetSubscrLimit.
