The parts of the policies are:
ˆ Classifier - Specifies the IP address of the node with a video
application. The classifier for Policy 17 specifies the address as a
source address since this classifier is part of a policy concerning
packets coming from the application. The classifier for Policy 32
specifies the address as a destination address because this classifier
is part of a policy concerning packets going to the application.
ˆ Flow Group - Specifies the new priority level of 4 for the packets. As
with the previous example, the packets leave the switch with the same
priority level they had when they entered. The new priority level is
relevant only while the packets traverse the switch. To alter the
packets so that they leave containing the new level, you would change
option 5, Remark Priority, to Yes.
ˆ Traffic Class - The packet stream is assigned a maximum bandwidth of
5 Mbps. Bandwidth assignment can only be made at the traffic class
level.
ˆ Policy - Specifies the traffic class and the port where the policy is to be
assigned.
