This feature lets you enable IP learning on selected ports. If this is enabled, the device checks the IP part of the packet to see the IP address of the source station.
You can have the same policies for these ports as usual.
If IP learning is disabled on a port, a station transmitting ARPs on that port will not be learned through an IP rule, even if it exists. This allows you to select the ports where you want the IP rules to have effect (for example, if stations on a particular port run a mix of protocols).
If you move a station without switching its IP learning off, it will be relearned when it transmits another ARP packet (the next time it tries to connect to any IP host that is not currently in its ARP cache). This is true only for IP learning rules; a MAC rule will not have this relearning.
