Configuring CoS Drop Profile Maps
A drop-profile map associates weighted random early detection (WRED) profiles for traffic of specified packet loss priorities with a scheduler. When you use a scheduler map to map a scheduler to a forwarding class, the drop profile map associated with the scheduler applies the specified WRED drop profile to traffic in the forwarding class that matches the specified packet loss priority.
Drop profile maps enable you to configure different drop profiles for traffic of different packet loss priorities within the same scheduler. You can associate different drop profiles with low-priority, medium-high priority, and high-priority traffic within a single scheduler, and then map that scheduler to a forwarding class. This applies the appropriate drop profile to traffic of each loss priority in a forwarding class. Drop profile maps apply to all traffic protocols.
To configure a drop-profile map:
For the desired scheduler, configure the traffic loss priority and specify the drop profile you want to use to control the drop characteristics for traffic of that loss priority:
[edit class-of-service] user@switch# set schedulers scheduler-name drop-profile-map loss-priority level protocol any drop-profile drop-profile-name
Note:QFX10000 switches do not support the
protocol anyportion of the configuration. Drop profiles apply to all protocols.
