MAC, IP & TCP/UDP with flow entries

3wizard — Thu, 27 Feb 2014 10:33:06 GMT

When HP VAN controller add flow entries in flow table, reactively. It only use MAC address in match field.
Now I want to see MAC, IP address and TCP/UDP in switch's flow tables. How do I push the flow entry with MAC, IP & TCP/UDP in HP 5900's flow tables.

Do you get the IP fields included when you set the "layer3.forward" setting to 'true' in the PathDaemon configuration?

Hi Expert,
After modify the setting to true in the PathDaemon configuration I can't still get the TCP/UDP port in flow entries. if the controller add TCP/UDP field reactively, I'd like to get how to do it.
Best Regards,

My apologies, it looks like having the "layer3.forward" setting enabled, it will only include the IPv4 source and IPv4 destination addresses in the forwarding flow-mod that gets pushed in response to a forwarded packet. From what I see, there is no code in the PathDaemon controller application (which paves paths by default) which will push flows which include TCP/UDP port numbers. If you'd want this kind of forwarding, you'd need to write a custom application that does include those fields in the forwarding decision.
