Hardware-accelerated sFlow

EOS-4.20.5F adds support for hardware-accelerated sFlow on compatible platforms. Without hardware acceleration, all sFlow processing is done in software, which means that performance is heavily dependent on the capabilities of the host CPU. Aggressive sampling rates also decrease the amount of processing time available for other EOS applications. With hardware acceleration, all sFlow processing is done in hardware using specialized chips, also called accelerators. These accelerators process sampled packets and send out sFlow datagrams just like the software agent, but because there is very little involvement from the CPU, and the chips are dedicated to sFlow, performance is higher and...

LANZ Notifying Mode on 7500R, 7280R series

This document describes the current status of LANZ on DCS-7500R, DCS-7280R and DCS-7020R, for both polling and notifying modes. It focuses on the differences with the 7500E and 7280E series. Please refer to the existing documentation (see https://eos.arista.com/eos-4-15-xf/lanz/) for configuring and using LANZ. As of 4.21.0F, LANZ adds notifying mode support for the DCS-7020R series, and by using the counter engines fixes the notifying mode issues that were present on DCS-7500R and DCS-7280R on earlier versions of EOS. Platform compatibility Platform Polling Mode support Notifying Mode support LANZ enabled by default Default mode DCS-7500E Yes (since EOS-4.14.0F) Yes (since EOS-4.15.0F)...
