Switch Configuration
Protocol settings and switch functionality
The "Switch Configuration" screen appears if you click the "Switch" folder icon. In this
screen, you specify which functionality is enabled on the IE switch and which protocols will
be used for managing data traffic.
Figure 4-48 Switch Configuration
In the upper part of the screen, you can enable or disable the following functions of the IE
switch:
An IE switch automatically learns the source addresses of the nodes connected to it. This
information is used in the IE switch to forward data frames to the nodes specifically involved.
This reduces the network load for the other nodes.
If an IE switch does not receive a frame whose source address matches a learned address
within a certain time, it deletes the learned address. This mechanism is known as aging.
Aging prevents frames being forwarded incorrectly, for example when an end device (e.g. a
programming device) is connected to a different switch port.
If you select Aging Enabled, an IE switch deletes the learned addresses automatically after a
selected time (aging time).
