The Workflow for WRED/DRR
To begin working with WRED objects, the first step is to create and configure a CoS queue group (which
includes DRR, or Distributed Round Robin). You can then apply the created CoS queue group to one or
multiple interfaces. At a time, only one CoS queue group can be applied to any number of interfaces.
At any given time, you also have the option to edit, delete, or change the association of a CoS queue
group.
Engine Type Support for WRED
If an attempt is made to apply a WRED policy to an engine 1 or 3 module, then the request will be refused
and an appropriate error message issued to the client. The full range of WRED functionality will be
supported for engine 0, 2, 4 and 4+ modules.
