For network monitoring and troubleshooting flow related issues, it is desirable to know the path, latency, queue and congestion information for flows at different times. The inband telemetry feature(INT), based on Inband Flow Analyzer RFC draft -IFA 2.0 and IFA 1.0(on some platforms) , is used to gather per flow telemetry information like path, per hop latency and congestion. INT is supported for both IPv4 and IPv6 traffic.

Mirror on drop is a network visibility feature which allows monitoring of MPLS or IP flow drops occurring in the ingress pipeline. When such a drop is detected, it is sent to the control plane where it is processed and then sent to configured collectors. Additionally, CLI show commands provide general and detailed statistics and status.

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".
