Hi Ben,
I have tied the steps and reference you had given, but failed. I had rephrased
the query with the changes I have tried, and the learning I have had after your
help.
Please find those commands being executed as part of that mail itself. -- see
below
Assigning IP address to the port (vlan1200) created under the main bridge
(cloudbr) is failing. Now after a machine restart and trying the same
configuration and commands, it pings the gateway address for a while, and then
it fails.
I request you to please go through the complete mail (-- see below) to
understand the whole scenario, and help me to pin out where I am going wrong.
Thanks!
Thanks & Regards,
Ashraf Khalid

Dear friends,
I have not found a solution yet, and feels it is a matter of some basic config
error. Kindly help!
Let me rephrase the scenario again:
I want to know procedure to setup bridge on top of an existing bond interface
which is configured using linux native bonding.
I have configured "bond0"
bond interface using eth1 and eth2 using mode=4 (alb) in the CentOS 6.4
host, and LACP configured in the physical switches (stacked).
Later I tested it by assigning an IP address to the bond0 bond interface, and
it seems to be working just fine! I could successfully ping the default gateway.
Please note that the physical switch ports to which eth1 & eth2 are connected
is configured as access ports for VLAN 1200.
Later
I removed the IP Address from bond interface (bond0) which I had
created (but retained the bonding configurations in the
/etc/sysconfig/network-scripts/ifcfg-bond0 ).
Now I want to create a main bridge named "cloudbr" using open vswitch on top of
this native linux bond interface (bond0), and finally create an internal port
named "vlan1200", assign an IP address to it, so as to connect from externally
for management purpose.
I have tried the same using ovs-vsctl command, but it is succeeds only for a
brief moment, and then fails. Please find the commands I had executed:
# ovs-vsctl add-br cloudbr
# ovs-vsctl add-port cloudbr bond0 tag=1200 vlan_mode=access
# ovs-vsctl add-port cloudbr vlan1200 tag=1200 -- set interface vlan1200
type=internal
# ifconfig vlan1200 192.168.120.100 netmask 255.255.255.0 broadcast
192.168.120.255 up
# ovs-vsctl show

Kindly guide me to find a solution to this issue which has been haunting me for
days together :-(
