database (e.g. via
controller. This will only be suitable for some situations,
though.
+Q: I configured ports on a bridge as access ports with different VLAN
+ tags, like this:
+
+ ovs-vsctl add-br br0
+ ovs-vsctl set-controller br0 tcp:192.168.0.10:6633
+ ovs-vsctl add-port br0 eth0
+ ovs-vsctl add-port br0 tap0 tag=9
+ ovs-vsctl add-port br0 tap1 tag=10
+
+ but the VMs running behind tap0 and tap1 can still communicate,
+ that is, they are not isolated from each other even though they are
+ on different VLANs.
+
+A: Do you have a controller configured on br0 (as the commands above
+ do)? If so, then this is a variant on the previous question, "My
+ OpenFlow controller doesn't see the VLANs that I expect," and you
+ can refer to the answer there for more information.
