Enable egress sFlow to sample traffic sent to any DANZ Monitoring Fabric (DMF) Recorder Node (RN) attached to the fabric. Examining these sampled packets on a configured sFlow collector allows the identification of post-match-rule flows recorded by the RNs without performing a query against the RNs. While not explicitly required, Arista Networks highly recommends using the DMF Analytics Node (AN) as the configured sFlow collector, as it can automatically identify packets sampled utilizing this feature.

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".

The sFlow VPLS extension adds support for providing VPLS-related information to sFlow packet samples, for VPLS forwarded traffic. Specifically, for customer traffic ingressing on a CE-facing PE interface in a VPLS deployment that uses statically configured LDP pseudowires, information such as the name of the VPLS instance and the ID of the pseudowire that the packet will egress over will be included in the sFlow datagram.

This feature adds support for configurable max sFlow datagram size. The current default max datagram size is 1400 bytes, which can cause some sFlow datagrams to be dropped when there is an MTU set. This feature enables the configuration of the max datagram payload size within the range of 200 to 1500 bytes to help avoid fragmentation. Note that this feature only configures software sFlow and is not supported on hardware-accelerated sFlow.

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.

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.
