As in RSVP-TE LSPs, it is possible to enable the collection of traffic statistics on SR-TE LSPs (using either a named LSP or SR-TE templates). However, traffic statistics are only available on egress of ingress LER. Also, traffic statistics cannot be recorded into an accounting file.
Unlike RSVP-TE LSP statistics, SR-TE LSP statistics are provided without any forwarding class or QoS profile distinction. However, traffic statistics are recorded and made available for each of the paths of the LSP (primary and backup). Statistic indexes are only allocated at the time the path is effectively programmed, are maintained across switch-over for primary and standbys only, and are released if egress statistics are disabled or the LSP is deleted.
