Verifying That the Analyzer Has Been Correctly Created
Verify that the analyzer named
created on the switch with the appropriate input interfaces, and appropriate output
interface.
You can verify the port mirror analyzer is configured as expected using the
command.

analyzer output is to a VLAN), is mirroring the traffic entering the
interfaces, and sending the mirrored traffic to the

J-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 J-EX4200 switches
Packets exiting a VLAN on J-EX8200 switches
You can analyze the mirrored traffic using a protocol analyzer application running on a
remote monitoring station if you are sending mirrored traffic to an analyzer VLAN.
This topic includes two related examples that describe how to mirror traffic entering
ports on the switch to the
a remote monitoring station. The first example shows how to mirror all traffic entering
the ports connected to employee computers. The second example shows the same
scenario, but includes a filter to mirror only the employee traffic going to the Web.
