Learning

Starting/stopping learning
With the automatic learning function, all connected devices are automatically entered in the
unicast filter table. As long as the "Start learning" function is enabled, all learned unicast
addresses are created immediately as static unicast entries.
The learning process is ended only after clicking the "Stop learning" button. With this
method, learning can take a few minutes or several hours in larger networks before all nodes
have really been learned. Only nodes that send packets during the learning phase are found.
By subsequently enabling the Port Lock function, only packets from the nodes known after
the end of the learning phase (static unicast entries) will be accepted at the relevant ports.
Note
If the Port Lock function was already active on individual ports prior to the automatic learning
phase, no addresses will be learned on these ports. This makes it possible to restrict
learning to certain ports. To do this, first enable the Port Lock function of the ports that are
not intended to learn addresses.
Steps in configuration
Learning addresses
1. Click the "Start learning" button to start the learning phase.
After starting the learning phase, the "Start learning" button is replaced by the "Stop
learning" button.
The device now enters the addresses of connected devices until you stop the function.
2. Click the "Stop learning" button to stop the learning function.
The button is once again replaced by the "Start Learning" button. The learned entries are
stored.
