Hey
I'm using the following script to create the bridge (OVS). As you can
see, I'm using
ovs-vsctl set bridge $NAME protocols=OpenFlow13
To set the version of OFP. Is there any other place where I have to
configure this? Because my app won't work anyways with OVS, here's the
version I'm using:
clt-mob-p-1093:/home/staff/aepp/unix # ovs-vsctl --version
ovs-vsctl (Open vSwitch) 1.10.0
Compiled May 6 2013 11:47:07
clt-mob-p-1093:/home/staff/aepp/unix #
usage()
{
cat << EOF
usage: $0 options
This script creates or deletes an Open vSwitch.
OPTIONS:
-h Show this message
-o Can be 'add' or 'del'
-n The name of the bridge
-p Amount of port numbers
-v Verbose
EXAMPLE:
# $0 -o add -n lan0 -p 5
# $0 -o del -n lan0 -p 5

}

if [ "$OP" == "add" ]
then
# create the bridge
ovs-vsctl add-br $NAME
# use OFP13
ovs-vsctl set bridge $NAME protocols=OpenFlow13
for tap in `seq 0 $PORTS`; do
ip tuntap add mode tap ${NAME}p$tap
done;

# remove all taps
for tap in `seq 0 $PORTS`; do
ip tuntap del ${NAME}p$tap mode tap
done;
else
usage
exit 1
fi
