Intended Audience
This manual is intended for people who want to want to configure the ZyWALL using the Web Configurator.
How To Use This Guide
· Read Chapter 1 on page 29 chapter for an overview of features available on the ZyWALL. · Read Chapter 3 on page 43 for web browser requirements and an introduction to the main components, icons and menus in the ZyWALL Web Configurator. · Read Chapter 4 on page 59 if you're using the installation wizard for first time setup and you want more detailed information than what the real time online help provides. · Read Chapter 5 on page 69 if you're using the quick setup wizards and you want more detailed information than what the real time online help provides. [. . . ] Inbound refers to the traffic the ZyWALL sends to a connection's initiator. Outbound refers to the traffic the ZyWALL sends out from a connection's initiator. Select one of the pre-defined DSCP values to apply or select User Defined to specify another DSCP value. The number following the "af" identifies one of four classes and one of three drop preferences. See Assured Forwarding (AF) PHB for DiffServ on page 309 for more details. Select preserve to have the ZyWALL keep the packets' original DSCP value. Select default to have the ZyWALL set the DSCP value of the packets to 0.

Chapter 28 Bandwidth Management
Table 132
LABEL
Inbound kbps
Configuration > Bandwidth Management
DESCRIPTION
Type how much inbound bandwidth, in kilobits per second, this policy allows the traffic to use. Inbound refers to the traffic the ZyWALL sends to a connection's initiator. If you enter 0 here, this policy does not apply bandwidth management for the matching traffic that the ZyWALL sends to the initiator. Traffic with bandwidth management disabled (inbound and outbound are both set to 0) is automatically treated as the lowest priority (7). If the sum of the bandwidths for routes using the same next hop is higher than the actual transmission speed, lower priority traffic may not be sent if higher priority traffic uses all of the actual bandwidth.
Outbound kbps
Type how much outbound bandwidth, in kilobits per second, this policy allows the traffic to use. Outbound refers to the traffic the ZyWALL sends out from a connection's initiator. If you enter 0 here, this policy does not apply bandwidth management for the matching traffic that the ZyWALL sends out from the initiator. Traffic with bandwidth management disabled (inbound and outbound are both set to 0) is automatically treated as the lowest priority (7). If the sum of the bandwidths for routes using the same next hop is higher than the actual transmission speed, lower priority traffic may not be sent if higher priority traffic uses all of the actual bandwidth.
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 traffic that matches this policy. Traffic with a higher priority is given bandwidth before traffic with a lower priority. The ZyWALL uses a fairness-based (round-robin) scheduler to divide bandwidth between traffic flows with the same priority. 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.
Maximize Bandwidth Usage
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. After each application or type of traffic gets its configured bandwidth rate, the ZyWALL uses the fairness- based scheduler to divide any unused bandwidth on the out-going interface amongst applications and traffic types that need more bandwidth and have maximize bandwidth usage enabled.
