This makes two of us. I've done everything as you have described and it simply does not work.

Are you actually seeing VLAN tagged traffic, or is the cisco switch just providing a normal stream?

At work we have hundreds of VLANs, but the servers don't get configured for this; we just configure them as normal; ie eth0. The network infrastructure does the VLAN decoding, the server doesn't have to.

Try configuring the machine as if it was a real LAN and forget about the VLAN.

If that doesn't work then what does 'tcpdump -i eth0' show you?
