RE: Multiple network segment monitor with Snort

["James Williams" <jwilliams () mail wtamu edu>]

If the box is connected to a cisco switch you can setup a port to
monitor as many, or as few vlans as you want and send that traffic to
the port that your snort box is connected to.

...and don't forget you're PCI backplane limits... I *think* a standard
PCI-based box is good for up to 4 100Mb Ethernet cards, and being picky
about card choices/etc can push that up to 6 100M cards - but beyond
that
you exceed the limits of the PC arch...?
