Hello,

We have Cisco UCS servers with CentOS 6.4 and OVS 1.10.0. Native ovs vlan
tags don't work with "enic" driver (I've tried newest one 2.1.1.42 from
cisco.com with no success). Therefore we use vlan-splinters.

Problem is that OVS removes all vlan interfaces (including our public
network) and recreates only its own.

Initially we have:

eth0 - 192.168.122.176/24
eth0.3000 - 10.0.0.1/24
eth1 - no IP

after executing:

ovs-vsctl add-br br100
ovs-vsctl add-port br100 eth1
ovs-vsctl set interface eth1 other-config:enable-vlan-splinters=true

*no eth0.3000 in system.*

In source code i've found that it shouldn't remove vlan interfaces if it
has assigned IPv4 address, but this doesn't work. Correct if i am wrong

Please help.

Thanks, Roman Sokolkov
