The parts of the policies are:
❑ Classifier - Defines the traffic flow by specifying the IP address of
the node with the voice application. The classifier for Policy 6
specifies the address as a source address since this classifier is part
of a policy for packets coming from the application. The classifier
for Policy 11 specifies the address as a destination address since
this classifier is part of a policy for packets going to the
application.
❑ Flow Group - Specifies the new priority level of 7 for the packets.
It should be noted that in this example the packets leave the
switch with the same priority level they had when they entered.
The new priority level is relevant only as 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.
❑ Traffic Class - No action is taken by the traffic class, other than to
specify the flow group. Traffic class has a priority setting that can
be used to override the priority level of packets, just as in a flow
group. If you enter a priority value in both places, the setting in
the flow group overrides the setting in the traffic class.
❑ Policy - Specifies the traffic class and the port to which the policy
is to be assigned. Policy 6 is applied to port 1 since this is where
the application is located. Policy 11 is applied to port 8 since this
is where traffic going to the application will be received.
