Hello, We suffering a problème about network switching between a physical world and a virtual world :
We have a x86 server, with 10Gb cards. On the vswitch we have add some cards to do the switching : ovs-vsctl add-bond brCentral ovsbond0 eth4 eth5 bond_mode=active-backup bond_updelay=10 bond_downdelay=10 lacp=off trunk=[0,2,3702] But appears a broblème : the switching works very good for untagged frames but doesn't work fort tagged vlan 2 frames ... So the VM never see the response for a simple arp request :( I've see the "ovs-vlan-bug-workaround eth4 on" but : ovs-vlan-bug-workaround: operation failed (kernel does not support the VLAN bug workaround) We have tested with "Emeluex oneConnect 10Gbps", module be2net and with braodcom bnx2x ... Any idea plz ?
