If you have access to the device that is routing, you can find the MAC address
from the ARP table. On a device running Junos, the command would be "show arp".
You could narrow down the results with the match filter ("show arp | match <ip
address>"). Then you can use "show ethernet-switching table brief" on the
EX2200 as you mentioned before.

Subject: [j-nsp] juniper switch ex2200 how to find port from ip address?
Hello everybody
I am relatively new to networking and I am currently managing a few EX2200
switches.
I need to find to which port a machine is connected to, but all I have is an IP
Address. I know that I can use show ethernet-switching table brief but
unfortunately I do not have the MAC address.
Any help would be greatly appreciated.
Thank you
