each department's traffic on a different egress queue. This is how the DiffServ inbound policy connects
to the CoS queue settings established below.

4. DiffServ inbound configuration: Attach the defined policy to interfaces 1/0/10 through 1/0/13 in the
inbound direction.

5. Set the CoS queue configuration for the (presumed) egress interface 1/0/14 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 interface 1/0/14, based on a normal destination address lookup for internet
traffic.
