Rate statistics

SR OS also provides traffic rate statistics. For RSVP-TE LSPs, including template-based LSPs, and MPLS-TP LSPs, the user performs one of the following options to enable that capability:

• configures an accounting policy that uses the combined-mpls-lsp-egress record name
• assigns that accounting policy to a specific LSP (or template)
• enables stats collection

The frequency at which the rate is determined is defined using the collection-interval keyword in the accounting policy. The minimum interval is currently 5 minutes.

Rate statistics are provided in packets per second and Mb/s. Rate statistics are provided as an aggregate across all paths of the LSP, which have a statistical index assigned, and for all forwarding classes in or out-of-profile.

Rate statistics are only available on the egress of the ingress LER. At least two samples are needed to determine a rate.
