EX Series switches allow you to configure port mirroring to send copies of packets to
either a local interface for local monitoring or to a VLAN for remote monitoring. You can
use port mirroring to copy these packets:
Packets entering or exiting a port
Packets entering a VLAN on EX2200, EX3200, EX4200, or EX4500 switches
Packets exiting a VLAN on EX8200 switches
To configure port mirroring on an EX Series switch using the J-Web interface:
Select >

The first part of the screen displays analyzer details such as the name, status, analyzer
port, ratio, and loss priority.
