Hardware Accelerated sFlow on 7280R3/7500R3/7800R3

Description EOS-4.24.0 adds support for hardware-accelerated sFlow on R3 systems. Without hardware acceleration, all sFlow processing is done in software, which means 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 on the switch ASIC itself, with little involvement from the CPU. Hence, it’s possible to support higher sampling rate without compromising CPU performance. Note that this is different from DCS-7280R2 and DCS-7500R2 systems, where a separate accelerator chip is used to provide hardware acceleration....

Accelerated Software Upgrade support on some 7280R platforms

Description ASU (or Accelerated Software Upgrade) is a feature that will minimize traffic loss when upgrading from one ASU-supported EOS version to a newer ASU-supported EOS version. During the upgrade process, the ASIC is kept active and will continue to forward traffic based on the data plane state. A brief loss of traffic is expected when the configuration from the new EOS image is applied to the ASIC. Note that the first supported version for this feature refers to the first version where the command is available. ASU cannot be performed from an older version to the first supported version....
