Chapter 9 Interfaces Each field is described in the table below. Table 124 Configuration > Network > Interface > Trunk > Add (or Edit) LABEL DESCRIPTION Name Load Balancing Algorithm This is read-only if you are editing an existing trunk. When adding a new trunk, enter a descriptive name for this trunk. You may use 1-31 alphanumeric characters, underscores (_), or dashes (-), but the first character cannot be a number. This value is case-sensitive. Select a load balancing method to use from the drop-down list box. 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. Load Balancing Index(es) Add Edit Remove Move # 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). This field is available if you selected to use the Least Load First or Spillover method. Select Outbound, Inbound, or Outbound + Inbound to set the traffic to which the Zyxel Device applies the load balancing method. Outbound means the traffic traveling from an internal interface (ex. LAN) to an external interface (ex. WAN). Inbound means the opposite. The table lists the trunk's member interfaces. You can add, edit, remove, or move entries for user configured trunks. Click this to add a member interface to the trunk. Select an interface and click Add to add a new member interface after the selected member interface. Select an entry and click Edit to modify the entry's settings. To remove a member interface, select it and click Remove. The Zyxel Device confirms you want to remove it before doing so. To move an interface to a different number in the list, click the Move icon. In the field that appears, specify the number to which you want to move the interface. 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. Click this table cell and select an interface to be a group member. Mode If you select an interface that is part of another Ethernet interface, the Zyxel Device does not send traffic through the interface as part of the trunk. For example, if you have physical port 5 in the ge2 representative interface, you must select interface ge2 in order to send traffic through port 5 as part of the trunk. If you select interface ge5 as a member here, the Zyxel Device will not send traffic through port 5 as part of the trunk. Click this table cell and select Active to have the Zyxel Device always attempt to use this connection. Weight Select Passive to have the Zyxel Device only use this connection when all of the connections set to active are down. You can only set one of a group's interfaces to passive mode. This field displays with the weighted round robin load balancing algorithm. Specify the weight (1~10) for the interface. The weights of the different member interfaces form a ratio. This ratio determines how much traffic the Zyxel Device assigns to each member interface. The higher an interface's weight is (relative to the weights of the interfaces), the more sessions that interface should handle. ZyWALL ATP Series User's Guide 328
