Xen users - Jan 2010 - bridge sends traffic to all interfaces

Hello
I have a xen node, everydays for a few minutes, the bridge will send
all income traffic to all interfaces, it makes our traffic statistics
incorrect,
Any help is appreciated.

Thanks.

I could be wrong about this, but this behavior may be designed such that the
bridge can learn the MAC addresses that are available on each of the interfaces.
You might also want to look into the open-vswitch project - if you''re
concerned about accurate traffic accounting and switch behavior, this may be
more to your liking.  It also features abilities for things like port
monitoring, which would allow you better visibility into the traffic on your
bridges (switches).

Nick, why didn''t you post about open-vswitch sooner :D
Something that can replace linux bridge directly, but has more
features? Awesome. Do you know if it also works on RHEL/Centos5?

Sorry - I thought it had already been discussed on this list :-).  Yes, it
replaces the Linux bridging functionality - in fact, it has a compatibility
layer that allows you to continue to use brctl and allows Linux network scripts
to function.  It''s still early in its development - it''s
stable, but has a long list of features that still need to be added.  Web site
is http://open-vswitch.org.  It should work on just about any Linux
distribution, although you may have to fidget with the kernel modules piece to
get it work.

Also, awesome.

How many list subscribers does it take to get a correct URL posted?  :-)
