Dell PowerConnect 8024 User Configuration Manual page 1129

5 Set the CoS queue configuration for the (presumed) egress 10-Gigabit
Ethernet interface 1/0/1 such that each of queues 1, 2, 3 and 4 get a
minimum guaranteed bandwidth of 25%. All queues for this interface use
weighted round robin scheduling by default. The DiffServ inbound policy
designates that these queues are to be used for the departmental traffic
through the assign-queue attribute. It is presumed that the switch will
forward this traffic to 10-Gigabit Ethernet interface 1/0/1 based on a
normal destination address lookup for internet traffic.
