When i have this configuration, it works! But i would not have to specified that it is native 35. Because my goal is to use severals vlan.
A little precision, with my co-workers we have found that there were a bug with tcpdump to see ethernet frame with tags ! So, with my first configuration (without native vlan on the cisco) i can see ARP request from my VM to my vswitch and to my cisco. But i haven't the ARP reply ... And if i force it by adding Mac address in arp table, it just send a ping request, but i don't receive the reply... Thank's a lot ;) Le Vendredi 23 Mars 2012 10:02 CET, Leland Vandervort <lel...@dev.discpro.org> a écrit: > > What is the rest of the port configuration on the cisco? > > To conform with your OVS configuration (specifically native untagged vlan35) > try: > > interface x/x/x > switchport > switchport trunk encapsulation dot1q > switchport mode trunk > switchport trunk native vlan 35 > switchport trunk allowed vlan 35,xxx > ! > > Any traffic for the "other" vlan (xxx) would of course need to be tagged. > > > > Le 23/03/2012 09:57, « Maxime JÉGO » <maxime.j...@netensia.fr> a écrit : > > > Hello erverybody, > > > > i have a KVM architecture with 2 Virtual machine called VM1 (with virtual > > interface vnet0) and VM2 (with virtual interface vnet1). > > > > I have created a bridge called br0 who contains a vlan called vlan35 (vid > > =35) > > > > My ovs configuration : > > > > ( - ovs-vsctl add-br br0 > > - ovs-vsctl add-port br0 eth1 trunk=35,200 > > - ovs-vsctl add-br vlan35 br0 tag=35 > > - ovs-vsctl add-port vlan35 vnet0 > > - ovs-vsctl add-port vlan35 vnet1 > > - ovs-vsctl add-port vlan35 vnet1 ) > > > > > > ovs-vsctl show : > > > > [root@******** ~]# ovs-vsctl show > > 93c8f900-cc8b-44a9-9081-613d79bc846e > > Bridge "br0" > > Port "vlan35" > > tag: 35 > > Interface "vlan35" > > type: internal > > Port "vnet0" > > tag: 35 > > Interface "vnet0" > > Port "br0" > > Interface "br0" > > type: internal > > Port "vnet1" > > tag: 35 > > Interface "vnet1" > > Port "eth1" > > trunks: [35, 200] > > Interface "eth1" > > > > > > > > > > My cisco switch configuration about this : > > > > - switchport trunk allowed vlan 35,xxx > > > > > > My problem : I can't ping my gateway (on my cisco switch) from my virtual > > machine VM1. > > I have identified the problem, I have only the icmp request traffic on eth1 > > and i haven't TAG on my frame.
