OVS switches with queues cannot register in ODL Li inventory.

2. Add a port :

1. ip tuntap add dev veth1 mode tap
2. ip link set dev veth1 up

3. Add an OVS switch and configure a queue for veth1 port :

1. ovs-vsctl add-br s1 – set Bridge s1 other_config:datapath-id=0000000000000001 – set-fail-mode s1 secure – add-port s1 veth1 – set Interface veth1 ofport_request=1 – set-controller s1 tcp:127.0.0.1:6633 ptcp:6634 – set bridge s1 other-config:disable-in-band=true – set bridge s1 protocols=OpenFlow13 – set port veth1 qos=@newqos – --id=@newqos create qos type=linux-htb queues=0=@q0 – --id=@q0 create queue other-config:min-rate=1 other-config:max-rate=1000
