These devices would be configured with mappings between classification
rules and service levels as shown in Table 100
:
Table 100 DiffServ Codepoints and Service Levels
When these devices receive packets they can simply examine the DiffServ
codepoint field of the packets to determine the service level, rather than
performing the more complex analysis that they are incapable of.
Components The following section describes the principles of traffic prioritization using
3Com Network Director.
Prioritize Network
Traffic Wizard
The Prioritize Network Traffic Wizard enables you to simplify traffic
prioritization configuration on your network without the need to
manually set up classifiers, dropping, queuing and marking.
The Prioritize Network Traffic Wizard is launched from Tools > Prioritize
Network Traffic.
The wizard allows you to select:
■ Servers that traffic should be prioritized to and from.
■ Servers whose traffic (transmitted or received) should be blocked on
your network.
■ Applications whose traffic you would like to prioritize.
■ Applications whose traffic should be blocked on your network.
In addition, the wizard automatically detects whether or not you have an
NBX telephony solution in your network and, if you do, automatically
selects NBX phone traffic for prioritization.
