be assigned to this context. If the context matches more than this value, the additional request for stat
indices from this context will be rejected. A background tasks monitors the ingress statistics
templates which have one or more matching LSP instances with unassigned stat index and assigns
one to them as they are freed.
Note the following rules when configuring an ingress statistics context based on template matching:
• max-stats, once allocated, can be increased but not decreased unless the entire ingress statistics
context matching a template name is deleted.
• In order to delete ingress statistics context matching a template name, a shutdown is required.
• An accounting policy cannot be configured or de-configured until the ingress statistics context
matching a template name is shut down.
• After deleting an accounting policy from an ingress statistics context matching a template name,
the policy is not removed from the log until a “no shut” is performed on the ingress statistics
context.
If there are no stat indices available at the time the session of the P2MP LSP matching a template
context is signaled and the session state installed by the egress LER, no stats are allocated to the
session.
Furthermore, the assignment of stat indices to the LSP names that match the context will also be not
deterministic. The latter is due to the fact that a stat index is assigned and released following the
dynamics of the LSP creation or deletion by the ingress LER. For example, a multicast stream crosses
the rate threshold and is moved to a newly signaled S-PMSI dedicated to this stream. Later on, the
same steam crosses the threshold downwards and is moved back to the shared I-PMSI and the P2MP
LSP corresponding to the S-PMSI is deleted by the ingress LER.
The no form deletes the ingress statistics context matching on the RSVP session name.
Parameters rsvp-session-name SessionNameString — Specifies the name of the RSVP P2MP session in the
format of “templateName-svcId”. This field can hold up to 64 characters.
sender sender-address — Specifies a string of 15 characters representing the IP address of the
ingress LER for the LSP.

Syntax [no] logger-event-bundling
Context configure>router>mpls
Description This feature merges two of the most commonly generated MPLS traps, vRtrMplsXCCreate and
vRtrMplsXCDelete, which can be generated at both LER and LSR into a new specific trap
vRtrMplsSessionsModified. In addition, this feature will perform bundling of traps of multiple RSVP
sessions, i.e., LSPs, into this new specific trap.
The intent is to provide a tool for the user to minimize trap generation in an MPLS network. Note that
the MPLS trap throttling will not be applied to this new trap.
The no version of this command disables the merging and bundling of the above MPLS traps.
