Set an IP with a mask in NOX #32

Closed ghost closed 10 years ago

I am writing an application with NOX. But I failed to send a flow-mod message with the dst_ip and a specified mask through NOX API all the time.

If I only set the IP field without any mask like this:

Flow *f = new Flow(); uint8_t ip_dst[4] = {10,0,0,1}; f->Add_Field("eth_type", 0x0800); f->Add_Field("ipv4_dst", ip_dst);

it works well. The rule will be inserted into the switches successfully

But if I add a mask for the dst_ip like this: Flow *f = new Flow(); uint8_t ip_dst[4] = {10,0,0,1}; uint8_t mask[4] = {255,255,255,0}; f->Add_Field("eth_type", 0x0800); f->Add_Field("ipv4_dst", ip_dst, mask); Nothing happened in the flow table

I wander if I have used the Add_Field function in the right way

Thanks in advance.
