Hi daniellima,
According to the product documentation, the S5731 does not support the sFlow feature. And no information about the sFlow capacity is found in the product documentation.

Thank you.

I saw here exactly this reference:

https://support.huawei.com/hedex/hdx.do?lib=EDOC1100126530AEI02128&docid=EDOC1100126530&lang=en&v=01&tocLib=EDOC1100126530AEI02128&tocV=01&id=EN-US_CONCEPT_0177112631&tocURL=resources%2fdc%2fdc%5ffd%5fsflow%5f0002%2ehtml&p=t&fe=1&ui=3&keyword=sflow

It is a problem for us because this is a unique new switch model with the possibility to add additional modules. We have a customer that needs a dedicated and specific Stack Module and not use the Uplink Interfaces for the stack use. Do you recommend another model?

Definition
Sampled Flow (sFlow) is a traffic monitoring technology that collects and analyzes traffic statistics.
Purpose
Enterprise networks differ from carrier networks in that they are smaller, more flexible, and more likely to be attacked. To prevent and limit service interruptions, enterprises require a traffic monitoring technique to locate unexpected traffic as well as the source of an attack in a timely manner.

sFlow provides interface-based traffic analysis, facilitating preventive maintenance on enterprise networks.

Huawei NetStream is also a technology that collects and analyzes traffic statistics. In NetStream, network devices need to collect and analyze traffic statistics and saves statistics to a cache. The statistics are exported when they expire or when the cache overflows. Compared with NetStream, sFlow does not require a cache, network devices only sample packets, and a remote collector collects and analyzes traffic statistics.
Architecture of an sFlow System
As shown in Figure 12-1, the sFlow system involves an sFlow agent embedded in a Huawei switch or router and a remote sFlow collector. The sFlow agent obtains traffic statistics from an interface using sampling and encapsulates them into sFlow packets. When an sFlow packet buffer overflows or an sFlow packet expires (expiry period 1 second), the agent sends the sFlow packets to the collector. The collector analyzes these sFlow packets and displays traffic statistics in a report.
