636CHAPTER 15: PRIORITIZING NETWORK TRAFFIC

There are several servers that 3Com Network Director will not allow you to select for blocking. In addition, there are various problems that may arise due to selecting servers for blocking. For more information see “Potential Hazards When Blocking Traffic To and From Servers” on page 659.

Applications Step

You can select applications for prioritization or blocking (See Figure 347). The Prioritize Network Traffic Wizard defines an application as a collection of classifier rules, each of which specifies one method of identifying traffic belonging to that application. These classifier rules specify the values that certain fields with a packet must have in order for that packet to be considered as belonging to the application.

Figure 347 Prioritize Network Traffic Wizard - Applications

When a device is configured with the classifier rules for a particular application only one of the rules needs to match a packet in order for the packet to be identified as belonging to that application.

Prioritized Applications — when you select an application for prioritization, traffic identified as belonging to that application is treated as more important than non-prioritized traffic by the configured devices. This means that the traffic will flow through the network faster and with less chance of being dropped.
