Configuring CoS Tail Drop Profiles (CLI Procedure)
Tail drop is a simple and effective traffic congestion avoidance mechanism. When you apply this mechanism to manage congestion, packets are dropped when the output queue is full.
To configure CoS tail-drop profiles, create a drop profile name (be-dp) and assign a fill level (25):
[edit class-of-service drop-profiles] user@switch# set be-dp fill-level 25
