You may want to check out sflow instead of using something
like port mirroring, with sflow(on sflow-enabled devices) it
samples enough data that you can get almost everything that flows
through the network and can do so at line rate on every port,
so even if your pushing 100Gbit on your switch you don't need
to worry about performance impact, something that wouldn't
be possible with port mirroring or cisco netflow.
