Hey,
Just repeated your config on my VM setup (two ubuntu 12.04 VMs on same
ESX host, eth3 directly linked),
~/alex_dev/openvswitch# ovs-vsctl show
a57a8953-c9fd-41c2-9cee-6bc57c2da649
Bridge "breth311"
Port "breth311"
Interface "breth311"
type: internal
Port "eth3.11"
Interface "eth3.11"
ovs_version: "2.3.90"
Worked for me, I can tcpdump from eth3.11...
Also, did you assign ip address to eth2.10? If you did, it should be
assigned
to br1's internal port.

This is a correct calling sequence,
