OVS uses the tc subsystem in the opposite direction that you're suggesting. Those ovs-vsctl commands modify fields in a database. ovs-vswitchd takes that configuration and makes tc calls to configure qos on Linux. If you call tc directly, OVS will not read your changes back and update the configuration database. If OVS does not provide the configuration knobs you want, you can directly call tc and skip the ovs-vsctl configuration entirely. I would be careful if you do both, though, since you're likely to get a broken configuration if both you and ovs-vswitchd are modifying tc. If you think your configuration is generally useful, you could propose changes to OVS to support what you're suggesting. --Justin _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
