tmnxBfdOnLspSessNoCpmNpResources

Table 8. tmnxBfdOnLspSessNoCpmNpResources properties
Property name	Value
Application name	BFD
Event ID	2005
Event name	tmnxBfdOnLspSessNoCpmNpResources

Default severity	minor
Message format string	The $tmnxBfdOnLspSessLinkType$ BFD session with local discriminator $tmnxBfdOnLspSessLclDisc$ on $subject$ could not be established because cpm-np session termination resources are not available
Cause	The tmnxBfdOnLspSessNoCpmNpResources notification is generated when a BFD on LSP session could not be established because the session requires a cpmNp or fp session termination resource (see TIMETRA-VRTR-MIB::vRtrIfBfdExtType), and no cpmNp or fp session termination resources are available.

tmnxBfdOnLspSessNoTailResources

Table 9. tmnxBfdOnLspSessNoTailResources properties
Property name	Value
Application name	BFD
Event ID	2006
Event name	tmnxBfdOnLspSessNoTailResources
SNMP notification prefix and OID	TIMETRA-BFD-MIB.tmnxBfdNotifications.6
Default severity	minor
Message format string	BFD on LSP session(s) could not be established because BFD on LSP session tail-end creation is administratively disabled, or the limit on the number of BFD on LSP session tail-ends has been reached (admin state = $vRtrLspBfdSession$, limit = $vRtrLspBfdMaxSessions$)
Cause	The tmnxBfdOnLspSessNoTailResources notification is generated when a BFD on LSP session could not be established by the LSP's tail-end system because the system limit on the number of session tail ends has been reached. If TIMETRA-VRTR-MIB::vRtrLspBfdSession is 'enabled(1)', the system limit on the number of session tail ends is TIMETRA-VRTR-MIB::vRtrLspBfdMaxSessions. If TIMETRA-VRTR-MIB::vRtrLspBfdSession is 'disabled(2)', the system limit on the number of session tail ends is zero. This notification is throttled using the following mechanism. In the initial state (e.g. at CPM startup), when the first failure is detected, tmnxBfdOnLspSessNoTailResources is raised, and a ten minute timer is started. When the timer expires, 1. tmnxBfdOnLspSessNoTailResources is raised if one or more failures occurred in the ten minute interval, and 2. A ten minute timer is started (and the process repeats). Any change to TIMETRA-VRTR-MIB::vRtrLspBfdSession and/or TIMETRA-VRTR-MIB::vRtrLspBfdMaxSessions restarts the process at the initial state.
Effect	One or more BFD on LSP sessions could not be established.
Recovery	Change TIMETRA-VRTR-MIB::vRtrLspBfdSession to 'enabled(1)', or increase TIMETRA-VRTR-MIB::vRtrLspBfdMaxSessions, or change the network configuration to reduce the number of active BFD on LSP session tail ends.
