How to get hostnames on dumb AP on luci?

PS:
the simplest thing is to create the file:
/etc/ethers

and copy it to all AP dumps

cat /etc/ethers

#
#  Lookup man 5 ethers for syntax documentation
#
#  Examples :
#       02:00:11:22:33:44       OpenWrt.lan
#       02:00:11:22:33:44       192.168.1.1
