Thanks. The first thing I see by simple inspection is the line "# CONFIG_VLAN_8021Q_MVRP is not set" but I'm not sure that would make a difference. I'll send the config file along to our repro team.

The vnet366 is configured as an access port on the openVSwitch and corresponds to eth1 on the VM. On the VM the configuration is : [root@YYY ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 TYPE=Ethernet BOOTPROTO=static ONBOOT=yes IPADDR=2.2.2.2 NETMASK=255.255.255.0 The physical Ethernet Port eth1 has the following configuration on the host : DEVICE=eth1 TYPE=Ethernet ONBOOT=yes BOOTPROTO=none The OVS successfully configures the VLAN and arp requests going out of eth1 to the network are tagged with VLAN 5. However it does not pick up the arp responses coming back from the other side. Let me know if any more details are needed.

I am on Centos 6.5 with the following kernel: 3.10.51-1.el6.elrepo.x86_64 I have the following intel driver in my setup.

When I try to ping another machine in the same network with vlan 5 , it seems that the arps are going out but the nic doesn't pick up the returning arps even though the other end is duly replying to the arps. [root@XXX ~]# tcpdump -i eth1 -ne arp tcpdump: WARNING: eth1: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 16:30:13.035965 52:54:00:3c:77:f5 > Broadcast, ethertype 802.1Q (0x8100), length 46: vlan 5, p 0, ethertype ARP, Request who-has 2.2.2.2 tell 2.2.2.3, length 28 16:30:14.038195 52:54:00:3c:77:f5 > Broadcast, ethertype 802.1Q (0x8100), length 46: vlan 5, p 0, ethertype ARP, Request who-has 2.2.2.2 tell 2.2.2.3, length 28 I can see the arps being responded to on the other end.
