DESCRIPTION
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. Weighted round robin is activated only when
the first group member interface has more traffic than it can handle.
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 ISG50 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.
Double-click an entry or select it and click Edit to open a screen where you can
modify the entry's settings.
To remove a member interface, select it and click Remove. The ISG50 confirms
you want to remove it before doing so.
