Chapter 32 Application Patrol Table 140 Application Policy Edit (continued) LABEL DESCRIPTION Priority This field displays when the inbound or outbound bandwidth management is not set to 0. Enter a number between 1 and 7 to set the priority for this application's traffic that matches this policy. The smaller the number, the higher the priority. The ZyWALL gives traffic of an application with higher priority bandwidth before traffic of an application with lower priority. The ZyWALL uses a fairness-based (round-robin) scheduler to divide bandwidth between applications with the same priority. Maximize Bandwidth Usage The number in this field is ignored if the incoming and outgoing limits are both set to 0. In this case the traffic is automatically treated as being set to the lowest priority (7) regardless of this field's configuration. This field displays when the inbound or outbound bandwidth management is not set to 0. Enable maximize bandwidth usage to let the traffic matching this policy "borrow" any unused bandwidth on the out-going interface. Log OK Cancel After each application gets its configured bandwidth rate, the ZyWALL uses the fairness- based scheduler to divide any unused bandwidth on the out-going interface amongst applications that need more bandwidth and have maximize bandwidth usage enabled. Select whether to have the ZyWALL generate a log (log), log and alert (log alert) or neither (no) when the application's traffic matches this policy. See Chapter 51 on page 833 for more on logs. Click OK to save your changes back to the ZyWALL. Click Cancel to exit this screen without saving your changes. 32.4 The Other Applications Screen Sometimes, the ZyWALL cannot identify the application. For example, the application might be a new application, or the packets might arrive out of sequence. (The ZyWALL does not reorder packets when identifying the application.) The Other (applications) screen controls the default policy for TCP and UDP traffic that the ZyWALL cannot identify. You can use source zone, destination zone, destination port, schedule, user, source, and destination information as criteria to create a sequence of specific conditions, similar to the sequence of rules used by firewalls, to specify what the ZyWALL should do more precisely. You can also control the bandwidth used by these other applications.This screen also allows you to add, edit, and remove conditions to this default policy. 540 ZyWALL USG 2000 User's Guide
