Hi OVS wizards. When adding multiple dpdk ports to a bridge where after adding one or two, I get a bridge_reconfigure caused by the if (ovsdb_idl_get_seqno(idl) != idl_seqno at line 2956 of bridge.c which in turn makes the datapath id to be unregistered. Then the bridge automatically assigns a new data path id and sends out a message to it¹s open flow controller (Ryu)
Trouble is, later the data path id¹s for those ports added before the reconfigure are now out of date so my data path id¹s for the ports will now be invalid This trouble cascades further if I am still in the middle of adding ports and flows after the unregister happens via open flow, the data path cannot be located so I have to throw some exceptions.. And then eventually we get a new data path id registration arrive over open flow. How do I : A) Stop the reconfigure from happening Or B) Get new data path id¹s for the ports previously attached so when I add flows via open flow commands they apply to known new data path id. Or C) handle the un-register / re register action gracefully via open flow controller Now there is mention in bridge.c of OFP_PORT_ACTION_WINDOW which is defined, but never used and I think was intended to help with just my scenario sounds a bit unfinished in this regard I am using head revision ovs I am using a Ryu app as a controller. With it¹s vsctl module for adding bridges and ports via ovsdb, and OpenFlow 1.3 protocol for openFlow controller for adding flows and collecting data. Cheers, Dave. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
