Thank you, Marty. It'll be very useful.
I looked into vlan tag filtering earlier, as I was playing with the CVS
version that supported vlan tags, and I learned that the newest version of
libpcap allows a bpf filter for 802.1q tags. The filter is, predictably,
"vlan". Ie, you can run snort with (on Solaris)
"snort <insert command line options here> vlan 4" to get just vlan 4
traffic. Mind, this required me to upgrade to libpcap 0.6.2, but it was
time for me to do that, anyway.
That kinda filtering is enough for me. Since I'd like to have different
sets of rules for each vlan, I'll just launch different instances of snort
for each vlan.

I added 802.1q protocol decoding/support on Wednesday, so I think you're
all set. Filtering on vlan tags hasn't been implemented, but I suppose
I could do something like that if I get the chance. No promises, but
I'll look at it...
