Ok, after running into the mostly useless Intel 510 "port mirroring" in
quite a few locations, I need some advice. What does one do when the
switch in use, cannot provide proper monitoring functions.

Most of the time I'm dealing with a relatively small amount of traffic,
on the order of 30-40Mbit at absolute peak times, and an average of
0.5-1Mbit. The HP ProCurve switches seem to handle this just fine with
their monitoring port setup.

I am using snort on midrange x86 boxes running Linux in most cases.

Thanks in advance.
