Usage Guidelines

Usage Scenario

A WRED drop profile defines WRED parameters for packets of different priorities. After the WRED drop profile is applied to an interface or queues on an interface, congestion avoidance is implemented. The drop-profile command creates a WRED drop profile or displays the WRED drop profile view.

Precautions

The S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support a maximum of 16 WRED drop profiles, and other switches support a maximum of 64 WRED drop profiles, including the default drop profile. The default drop profile can be modified but cannot be deleted.

Follow-up Procedure

Set parameters for the WRED drop profile.

Run the color command in the WRED drop profile view to set WRED parameters for packets of different priorities.
Apply the WRED drop profile to an interface or queues on an interface.

Example
