Hi, Some more information : When I use TCPDUMp on the physcal interface user by openvswitch : - I see the vlan ID when the packet leave openvswitch (ARP request) - I didn't see the vlan ID when the packet arrive (ARP respond)
It's like the vlan was not transmit to openvswitch (I clearly see that the ARP answer is dropped by ovs) Regard, 2011/9/30 Benoit ML <[email protected]> > Hello, > > We suffering a problème about network switching between a physical world > and a virtual world : > > We have a x86 server, with 10Gb cards.
