Tag :: Sampled Flow Tracking

RDMA over converged ethernet version 2 (RoCEv2) is a UDP protocol for transferring memory blocks between compute nodes. It is used for AI applications. RoCEv2 aware sampled flow tracking with IPFIX export is an enhancement that allows customers access to RoCEv2 flow information, for the purposes of analyzing and monitoring traffic associated with AI workloads.

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"
