DESCRIPTION
This field displays the label to identify the trunk.
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 SBG 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.
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 SBG 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.
