I wasn't involved in the standardization of OpenFlow 1.1, but I'd guess that groups were intended to replace this feature. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss

We also notice that it's the OpenFlow protocol (later version) does not support this bit. But we wonder why it's removed from the protocol? It's useless? Or we have an alternative to cover this.

[ovs-discuss] Why no-flood is not supported in later openflow versions?
Hi, In the openflow, we set no-flood PodMod operation through openflow 1.0; for later openflow versions, no-flood is dropped. We can refer to below two macro definitions. #define OFPPC10_ALL (OFPPC_PORT_DOWN | OFPPC10_NO_STP | OFPPC_NO_RECV | \ OFPPC10_NO_RECV_STP | OFPPC10_NO_FLOOD | OFPPC_NO_FWD | \ OFPPC_NO_PACKET_IN) #define OFPPC11_ALL \ (OFPPC_PORT_DOWN | OFPPC_NO_RECV | OFPPC_NO_FWD | OFPPC_NO_PACKET_IN) Would like to know why no-flood is not one of the common flags? Or do we have any other BKM to supersede such port config? Thanks, Jianfeng ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
