By default, if you configure no drop profiles, RED is still in effect and functions as the primary mechanism for managing congestion. In the default RED drop profile, when the fill-level is 0 percent, the drop probability is 0 percent. When the fill-level is 100 percent, the drop probability is 100 percent.
As a backup method for managing congestion, tail dropping takes effect when congestion of small packets occurs. On M320 and T-series platforms, the software supports tail-RED, which means that when tail dropping occurs, the software uses RED to execute intelligent tail drops. On other platforms, the software executes tail drops unconditionally.
