Message format string

The state of deterministic prefix-map map $tmnxNatDetPfxMapAddr$/$tmnxNatDetPfxMapAddrPrefixLength$ type $tmnxNatDetPfxMapSubType$ nat-policy '$tmnxNatDetPfxMapNatPolicy$' start $tmnxNatDetMap2InStart$ end $tmnxNatDetMap2InEnd$ changed to $tmnxNatDetMap2OperState$ - $tmnxNatNotifyDescription$

Cause

The cause is explained in the tmnxNatNotifyDescription.

Effect

While the operational state is down, subscribers matching the prefix cannot use deterministic NAT; if configured so, they can fall back on another NAT policy.

Recovery

The recovery action depends on the cause.

SNMP notification prefix and OID

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.

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.

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.

Cause

The tmnxNatInAddrPrefixBlksFree notification is sent when all port blocks allocated to one or more subscribers associated with a particular set of inside addresses are released by this system. The type of subscriber(s) is indicated by tmnxNatNotifySubscriberType. The set of inside IP addresses is associated with the virtual router instance indicated by tmnxNatNotifyInsideVRtrID and is of the type indicated by tmnxNatNotifyInsideAddrType. The set of inside IP addresses consists of the address prefix indicated with tmnxNatNotifyInsideAddr and tmnxNatNotifyInsideAddrPrefixLen unless these objects are empty and zero; if tmnxNatNotifyInsideAddr is empty and tmnxNatNotifyInsideAddrPrefixLen is zero, the set contains all IP addresses of the indicated type. The values of tmnxNatNotifyMdaChassisIndex, tmnxNatNotifyMdaCardSlotNum and tmnxNatNotifyMdaSlotNum identify the ISA MDA where the blocks were processed. All notifications of this type are sequentially numbered with the tmnxNatNotifyPlSeqNum. This type of notification is typically the consequence of one or more configuration changes; the nature of these changes is indicated in the tmnxNatNotifyDescription.

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.

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.

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.

Default severity

warning

Message format string

The Large Scale NAT activity changed to $tmnxNatPlLsnRedActive$ for pool $tmnxNatPlName$ - $tmnxNatNotifyDescription$

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.

The Virtual NAT Application $tmnxNatEsaNum$/$tmnxNatEsaVappNum$ is now $tmnxNatNotifyTruthValue$ in group $tmnxNatIsaGrpId$ .

Cause

The tmnxNatVappActive notification is sent when the value of the object tmnxNatVappStatOperState changes from 'primary' to any other value, or the other way around. The value 'primary' means that the Virtual NAT Application is active in the group.

Message format string

The Virtual NAT Application $tmnxNatEsaNum$/$tmnxNatEsaVappNum$ in group $tmnxNatIsaGrpId$ has detected load sharing errors and has dropped $tmnxNatNotifyCounter$ more packets.

Cause

The ingress IOM hardware does not support a particular NAT function's load-balancing, for example an IOM-2 does not support deterministic NAT.

Effect

The Virtual NAT Application drops all incorrectly load-balanced traffic.

Recovery

Upgrade the ingress IOM, or change the configuration.

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.
