Adaptive sampling fallback

You can use the CLI option "adaptive-sampling fallback" in sFlow monitoring configurations to back up the adaptive sampling rate on switch interfaces. Adaptive sampling uses a binary back-off algorithm to reduce the sampling loads on the selected interfaces. However, if the sampling rate suddenly increases because of a spike in traffic, it does not revert to the previously configured value even after traffic stabilizes. Adaptive sampling fallback uses a binary backup algorithm to back up and decrease the sampling rate without affecting normal traffic.
