Dear Aneesh, I'm also using hp3500 with ryu controller... unfortunately the OpenFlow implementation in those switches is limited and not very well documented.
Table 100 in the hp3500 is devoted only for matches executed in hardware. While table 200 is for matches executed in software. Following the documentation mac_destination field is not matched in hardware, so you cannot install a flow matching mac_destination in table 100. This explain why you are able to install it in table 200. Conversely, for instance, ip_destination is matched in hardware, so you can match ip_destination in table 100. A workaround to match mac_destination field can be: - push a flow on table 100 matching in_port with istruction goto table 200 - push a flow on table 200 matching mac_destination Following hp documentation the fields that are matched in hardware in the hp 3500 are: - in port - vlan id - ethernet type - ip src - ip dst - ip proto - ip dscp - tcp/udp src - tcp/udp dst Let me nkow if this helped you.
