Hi All, I got confused with the release notes section of OpenFlow Specification. In specification 1.3.1, section B.6.8, the IEEE 802.1D Spanning Tree Protocol configuration flags has been introduced in release 0.8.9 via the port structure enum ofp_port_config. While it has never been later discussed it seems that some of these flags have been removed, as mentioned in section A.2.1 they are not in the enum ofp_port_config field.
I also noted that there is a paragraph (repeated from the first specifications up to now) that says: "In general, the port config bits are set by the controller and not changed by the switch. Those bits may be useful for the controller to implement protocols such as STP or BFD. If the port config bits are changed by the switch through another administrative interface, the switch sends an OFPT_PORT_STATUS message to notify the controller of the change." I am wondering if STP flags are still supported in the latest Specification or not? If not shouldn't it be mentioned in the release notes appendix B that in which release they have been removed? Thanks, Navid
