Configuring Rsvp Lsp Statistics At Ingress Ler - Nokia 7705 SAR-W Series Manual

MPLS and RSVP-TE
3.3.2.1
At the ingress LER, statistics are configured in the egress data path of an originating
LSP with the config>router>mpls>lsp>egress-statistics command in the LSP
configuration at the head-end node. Statistics collection in the egress data path is
enabled after the user executes the no shutdown command in the egress-
statistics context. By default, this function is in a shutdown state.
Statistics cannot be configured if the LSP name contains a colon (:), which is used
as a field separator by the ingress LER for encoding the LSP and path names into
the RSVP Session Name field in the Session_Attribute object.
The no form of the egress-statistics command disables statistics collection in the
egress data path and removes the accounting policy association from the RSVP
LSP. Users can choose to disable statistics in the egress data path while keeping the
accounting policy association of the RSVP LSP with the
config>router>mpls>lsp>egress-statistics shutdown command.
The same set of counters are updated for packets forwarded over any path of the
LSP. In the steady state, counters are updated for packets forwarded over the active
path of the LSP. The active path can be the primary path, one of the secondary paths,
the FRR detour path, or the FRR bypass path when the head-end node is also the
PLR.
The LSP counters are maintained over the lifetime of the LSP as long as statistics
are enabled. The user can clear the counters with the
clear>router>mpls>lsp-egress-stats [lsp-name] command.
