Starting from 4.27.2F, IPFIX sampling introduced the capability to report BGP metadata for routes resolving over various tunnel types (ISIS-SR tunnels, NexthopGroups, etc).  For example BGP over ISIS-SR - BGP nexthop reported: 100.0.0.1

This document describes a new feature of Arista Analytics offering the ability to consolidate Netflow V9 and IPFIX records by grouping those sharing similar identifying characteristics within a configurable time window.

NDR switch sensor aka “monitor security awake” feature provides deep network analysis by doing deep packet inspection of some or all packets of traffic that's forwarded by the switch.

This document describes a new feature of Arista Analytics that combines Netflow and IPFIX records containing application information with Netflow and IPFIX records containing flow information.This feature improves the visibility of data per application by correlating flow records with applications identified by the flow exporter.

A new feature of Arista Analytics offers the ability to upsample traffic volume sampled by NetFlow V9/IPFIX and SFlow.This feature provides a better visibility of traffic volumes by approximating the number of bytes and packets from samples collected by the NetFlow V9/IPFIX or SFlow sampling protocols. It provides those approximation statistics along with the ElasticSearch statistics. The feature bases the approximations on the flow exporter’s sampling rate or a user-provided fixed factor.

Sampled flow tracking with IPFIX export is supported on most of the Arista platforms. User configured sampling rate is used for sampling in ingress and/or egress direction on the configured interfaces. An EOS software agent on CPU processes samples received from hardware, samples are used to create flow records that are exported to IPFIX collectors. Refer to Sampled flow tracking TOI for additional details.

Network administrators require access to flow information that passes through various network elements, for the purpose of analyzing and monitoring their networks. This feature provides access to IP flow information by sampling traffic flows in ingress and/or egress directions on the interfaces on which it is configured. The samples are then used to create flow records, which are exported to the configured collectors in the IPFIX format. Egress Flow tracking is supported from EOS-4.29.0F on the DCS-7170B-64C series and supported on 7280, 7500 and 7800 series platforms from EOS-4.31.1".

This feature extends sampled flow tracker to support the selective sampling of certain traffic types (specified globally), such as routed IPv4, routed IPv6, and MPLS pop and route IPv4, per interface. The feature is applicable on interfaces, subinterfaces, port channels, and port channel subinterfaces.

This feature allows Octa to act as a collector for IPFIX and sFlow datagrams and to aggregate and stream the collected data in response to a gNMI subscription. Octa is a process in EOS which combines OpenConfig and certain TerminAttr functionality, primarily with the intent of servicing gNMI requests for OpenConfig paths and for "EOS native" paths.
