ovs-vswitchd.conf.db(5) explains how to configure HTB and HFSC on OVS. You can use OpenFlow to assign packets to queues, if that's what your question about source address is getting at. ovs-ofctl(8) has some information on how that can work.

Policing happens on ingress.

If you enable hardware offloads during your tests, then necessarily the testing of OVS will test the hardware offloads. > > 6) Are all 4 support in OVS 1.2.2, what topology you used to test > this? > > Tunneling:- > > GRE > > GRE Over IPSec > > CAPWAP > > IPSec > > Yes, all of these are supported.

Please see ovs-vswitchd.conf.db(5) for setup information. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
