[j-nsp] juniper switch ex2200 how to find port from ip address?

[Edward Dore]

You need to find the entry for that IP address in the ARP table on whatever device(s) are terminating the L3 connectivity for that subnet. That will then give you the MAC address that you can look up in the ethernet-swtiching-table on the EX2200.
