Chapter 10 Interfaces Table 132 Configuration > Network > Interface > Trunk > Add (or Edit) (continued) LABEL DESCRIPTION OK Click OK to save your changes back to the Zyxel Device. Cancel Click Cancel to exit this screen without saving. 10.14.2 Configuring the System Default Trunk In the Configuration > Network > Interface > Trunk screen and the System Default section, select the default trunk entry and click Edit to open the following screen. Use this screen to change the load balancing algorithm and view the bandwidth allocations for each member interface. Note: The available bandwidth is allocated to each member interface equally and is not allowed to be changed for the default trunk. Figure 280 Configuration > Network > Interface > Trunk > Edit (System Default) Each field is described in the table below. Table 133 Configuration > Network > Interface > Trunk > Edit (System Default) LABEL DESCRIPTION Name Load Balancing Algorithm This field displays the name of the selected system default trunk. Select the load balancing method to use for the trunk. Select Weighted Round Robin to balance the traffic load between interfaces based on their respective weights. An interface with a larger weight gets more chances to transmit traffic than an interface with a smaller weight. For example, if the weight ratio of wan1 and wan2 interfaces is 2:1, the Zyxel Device chooses wan1 for 2 sessions' traffic and wan2 for 1 session's traffic in each round of 3 new sessions. Select Least Load First to send new session traffic through the least utilized trunk member. # Member Select Spillover to send network traffic through the first interface in the group member list until there is enough traffic that the second interface needs to be used (and so on). The table lists the trunk's member interfaces. This table is read-only. This column displays the priorities of the group's interfaces. The order of the interfaces in the list is important since they are used in the order they are listed. This column displays the name of the member interfaces. ZyWALL USG Series User's Guide 400
