RE: [Xen-users] xen bridged network config woes [repost w/apology]

Thank you Curtis-I've forwarded your email to them and I'm waiting for a

That said, while Googling, I found another interesting tcpdump
incantation that I tried, and I'd appreciate some insight into what its
output means:

root@dom0:~# tcpdump -nvvi vif2.0
tcpdump: WARNING: vif2.0: no IPv4 address assigned
tcpdump: listening on vif2.0, link-type EN10MB (Ethernet), capture size

0 packets dropped by kernel

This raises three questions:

1. Do I care about that warning on the top, "vif2.0: no IPv4 address
2. What does "802.1d unknown version" mean?
3. What does the "SNAP unnumbered" message mean?
