Return MAC address given the IP address

RouterOS Scripting

Hi All

Could any script guru advise on the right syntax for using the find command to return a MAC address from the /IP ARP list given the ip address?

many thanks.

/ip arp get [/ip arp find address=$ip] mac-address

(assuming $ip is a local or global variable with the IP address)

That didn’t work for me, i found that the below did.

:global macaddy [get [find address=172.16.1.11] mac-address]]
:put $macaddy
