Hi, I am using OpenFlow version 1.3. I want allow flow rules in the switch to match packets with a specified TTL value. Now, the Flow Match Structure available here <https://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html> does not allow matching on TTL value. I want to know how can I introduce custom match in hardware switch via RYU controller. I have been searching a lot. There are experimenter mach fields that can somehow work. The switch i'm using, ARUBA 2930F, has explanation in the Last topic of chapter 8, Custom Maches <https://support.hpe.com/hpsc/doc/public/display?docId=a00050280en_us>, about how I can match certain bits of a specific header. However, I am not sure how to achieve this via RYU. Kindly share if there's some example that I can follow.
Looking forward to hearing from you. Best Regards, Ramzah Rehman
