Thanks Harsh! This solves the mystery for me. I am now also less concerned about VLAN tag 4095 as it is used for internal communication only.
Now to my real problem. we are experiencing periodical packet drops for signification time. Nothing stand out in ovsdb-server.log or ovs-agent.log or neutron l3-agent.log ovs-vswitchd.log shows lots of warning with system@ovs-system: lost packet on channel xxx messages. This condition is causing loss of connectivity. So any help or insight in to this problem is greatly appreciated.

There is 1 more bridge br-tun who should have vxlan flows. For more info.

We are using OVS-vxlan in open stack. My question is why do I see tag (VLAN tag?) in ovs-vsctl output when I am using vxlan for my overlay networks. Also, what concerns me is the tag 4095? This tag shouldn't be used unless it is used for some local / management traffic. Because this has more to do with how OpenStack configures OVS than it does with OVS itself, you may have better luck asking about this on an OpenStack mailing list. discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss -- Sent from my Android device with K-9 Mail.
