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 feature allows egress sFlow sampling to be enabled per a subinterface. The egress sFlow sampling per a subinterface configuration will only have effect when egress sFlow sampling is disabled on the parent interface as egress sFlow sampling on the parent interface includes traffic on all subinterfaces.

The pre-existing "show sflow" command has a "Number of samples" field that indicates the total number packets sampled across all sFlow enabled interfaces. This feature will add finer granularity by allowing users of software sFlow to view the number of packets sampled at each sFlow enabled interface in the ingress and egress directions.
