meaning of ip local-proxy-arp ?

I would like to understand this feature : "IP LOCAL-PROXY-ARP" on VLAN level.

It seems that it replies positively to all arp requests that are sent to devices within this VLAN. Meaning, this arp request gets two arp replies : the one from the device, which is then overruled by a second arp reply from the dell switch. This causes all unicast traffic to be misleaded to the switch instead of the the destination device, resulting in ICMP redirects and so on.

What is the aim of this feature ?

It is not at all documented in the CLI Reference Guide.

Thanks a lot !
