ˆ Traffic Class - No action is taken by the traffic class, other than to
specify the flow group. Traffic class has a priority setting you can use
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.
ˆ Policy - Specifies the traffic class and the port to which the policy is to
be assigned. Policy 6 is applied to port 1 because this is where the
application is located. Policy 11 is applied to port 8 because this is
where traffic going to the application will be received.
Video
Applications
Video applications typically require a larger bandwidth than voice
applications. Video applications can be set up to have a high priority and
buffering, depending on the application.
This example creates policies with low latency and jitter for video streams
(for example, net conference calls). The policies in Figure 15 assign the
packets a priority level of 4. The policies also limit the bandwidth for the
video streams to 5 Mbps to illustrate how you can combine a change to the
priority level with bandwidth restriction to further define traffic control. The
node containing the application has the IP address 149.44.44.44. Policy
17 is assigned to port 1, where the application is located, and Policy 32 is
assigned to port 8 where packets destined to the application enter the
switch.
