Verifying That the Analyzer Has Been Correctly Created
Verify that the analyzer named
the appropriate input interfaces and appropriate output interface.
To verify that the analyzer is configured as expected while monitoring all employee traffic
on the source switching device, run the
the source switching device. The following output is displayed for this configuration
example.

This output shows that the
size of the original packet that were mirrored is 128, the state of the configuration is
which indicates proper state and that the analyzer is programmed, and the analyzer is
mirroring the traffic entering ge-0/0/0.0 and ge-0/0/1.0, and is sending the mirrored
traffic to the VLAN called remote-analyzer.
If the state of the output interface is
value of will be down and the analyzer will not be able to mirror traffic.

EX9200 switchesallow you to configure mirroring to send copies of packets to either a
local interface for local monitoring or to a VLAN for remote monitoring. You can use
mirroring to copy these packets:
