[ovs-discuss] seeking help

Wed Apr 1 17:55:45 UTC 2015

Hi,
I went through /users/peertest/openvswitch-2.3.0/vswitchd/vswitch.ovsschema
this has a checksum and a version and lots of tables.

Do i need to make any changes in here??

Please help why do the following lines give error???

Kindly help!!

#ovs-vsctl add-br br-int

sudo ovs-vsctl add-br OVSbr1

sudo ovs-vsctl add-br OVSbr2

Thanks & Regards
Sanghamitra
