FILTER

tFilterApplyPathProblem

Table 1. tFilterApplyPathProblem properties
Property name	Value
Application name	FILTER
Event ID	2008
Event name	tFilterApplyPathProblem
SNMP notification prefix and OID	TIMETRA-FILTER-MIB.tFilterNotifications.8
Default severity	minor
Source stream	main
Message format string	Problem in $tFltrPrefixListType$ prefix-list $tFltrPrefixListName$ for apply-path $tFltrApplyPathSource$ $tFltrApplyPathIndex$: $tFilterAlarmDescription$
Cause	Failed to add prefix/prefixes specified by the apply-path rule to the prefix list likely due to insufficient resources.
Effect	Prefix list does not contain all prefixes specified by the apply-path rule.
Recovery	Release resources by removing unnecessary prefixes or specify more specific apply-path rule.

tFilterEmbeddingOperStateChange

Table 3. tFilterEmbeddingOperStateChange properties
Property name	Value
Application name	FILTER
Event ID	2011
Event name	tFilterEmbeddingOperStateChange
SNMP notification prefix and OID	TIMETRA-FILTER-MIB.tFilterNotifications.11
Default severity	minor
Source stream	main
Message format string	The operational state of the embedded filter ID $tFilterEmbeddedRefEmbeddedFltrId$ in the embedding filter $tFilterEmbeddedRefFilterType$ ID $tFilterEmbeddedRefInsertFltrId$ has changed to $tFilterEmbeddedRefOperState$.
Cause	This notification may be triggered for the following reasons: 1) An attempt to embed an embedded filter into embedding filter was done. 2) An attempt to recover an embedding that is operationally down was done. 3) An attempt to change the admin state of an embedding was done. 4) The operational state of an embedding has changed to inactive due to lack of resources.
Effect	The effect depends on the new state. If the new state is 'active', the embedding of the filter was successful. If the new state is 'embedFailedNoResources' the embedding was not successful due to lack of resources. If the new state is 'inactive' and the previous state was 'active' then the embedded entries were removed. Otherwise the embedding filter was not changed.
Recovery	If the new state is 'active' or 'inactive', no action is required. If the new state is 'embedFailedNoResources', an attempt to recover the operational state can be done by removal and reapplication of the embedding.

tFilterEmbedFlowspecOperStateChg

Table 4. tFilterEmbedFlowspecOperStateChg properties
Property name	Value
Application name	FILTER
Event ID	2015
Event name	tFilterEmbedFlowspecOperStateChg
SNMP notification prefix and OID	TIMETRA-FILTER-MIB.tFilterNotifications.14
Default severity	minor
Source stream	main
Message format string	The operational state of the embedded FlowSpec rules of virtual router $tFilterEmbedFlowspecRtrId$ in the embedding filter $tFilterEmbedFlowspecFilterType$ ID $tFilterEmbedFlowspecInsertFltrId$ has changed to $tFilterEmbedFlowspecOperState$.
Cause	This notification may be triggered for the following reasons: 1) An attempt to embed a set of flowspec rules into an embedding filter was done. 2) An attempt to recover a flowspec rules embedding that is operationally down was done. 3) An attempt to change the admin state of a flowspec rules embedding was done. 4) The operational state of a flowspec rules embedding has changed to inactive due to lack of resources.
Effect	The effect depends on the new state. If the new state is 'active', the embedding of a set of flowspec rules was successful. If the new state is 'embedFailedNoResources' the embedding was not successful due to lack of resources. If the new state is 'inactive' and the previous state was 'active' then the set of flowspec rules were removed. Otherwise the embedding filter was not changed.
Recovery	If the new state is 'active' or 'inactive', no action is required. If the new state is 'embedFailedNoResources', an attempt to recover the operational state can be done by removal and reapplication of the flowspec rules embedding.

Message format string	The operational state of the embedded open-flow switch $tFilterEmbedOpenflowOfsName$ in the embedding filter $tFilterEmbedOpenflowFilterType$ ID $tFilterEmbedOpenflowInsertFltrId$ has changed to $tFilterEmbedOpenflowOperState$.
Cause	This notification may be triggered for the following reasons: 1) An attempt to embed an open-flow switch into an embedding filter was done. 2) An attempt to recover an open-flow embedding that is operationally down was done. 3) An attempt to change the admin state of an open-flow embedding was done. 4) The operational state of an open-flow embedding has changed to inactive due to lack of resources.
Effect	The effect depends on the new state. If the new state is 'active', the embedding of an open-flow switch was successful. If the new state is 'embedFailedNoResources' the embedding was not successful due to lack of resources. If the new state is 'inactive' and the previous state was 'active' then the open-flow switch entries were removed. Otherwise the embedding filter was not changed.
Recovery	If the new state is 'active' or 'inactive', no action is required. If the new state is 'embedFailedNoResources', an attempt to recover the operational state can be done by removal and reapplication of the open-flow embedding.

Cause	The tFilterRadSharedFltrAlarmRaised notification is generated when the number of Radius Shared Filters that are dynamically created in the system increases to the configured high watermark for the indicated filter.
Effect	No direct effect, however the system may run out of filter resources.
Recovery	The way in which dynamically filters are used in the system/network may need to be reconsidered.
