Aging Enabled
A SCALANCE X-200RNA automatically learns the source addresses of the nodes connected
to it. This information is used in the SCALANCE X-200RNA to forward data frames to the
nodes specifically involved. This reduces the network load for the other nodes.
If a SCALANCE X-200RNA does not receive a frame whose source address matches a
learnt address within a certain time, it deletes the learnt address. This mechanism is known
as aging. Aging prevents frames being forwarded incorrectly, for example when an end
device (for example a programming device) is connected to a different switch port.
If the check box is not enabled, a SCALANCE X-200RNA does not delete learnt addresses
automatically.
Aging Time [sec]
Here, you enter the time after which the SCALANCE X-200RNA deletes an address if it has
not received frames with the corresponding sender address.
Here, the aging time can be set as required within the range from 1 to 655 seconds.

Port status
Overview of the configuration of the ports
The "Port Status" screen appears if you click the "Ports" folder icon.
The screen shows the configuration for data transfer for all ports of the SCALANCE X-
200RNA.
