Re: [pox-dev] sending packets on all ports of the controller

I had to try couple of times to replicate the issue. It is OFP-OFP-ARP and both packet-outs are carrying arp replies. I will recheck my program. Cheers! Durga On Wed, Nov 20, 2013 at 2:53 PM, Murphy McCauley wrote: > > On Nov 19, 2013, at 7:04 PM, durga wrote: > > Hello All, > > reserved

Re: [pox-dev] manage events in Pox

There are two possible ways IMHO.1. Implement the PacketIn event and trigger subsequent events (AlertDDos) when circumstances match. The subsequent events execute the necessary activity. 2. Implement the PacketIn event and have a lookup tables to determine the action when circumstances match. The c

Re: [pox-dev] buffer_id is None?

Hi, Murphy, It turns out that I didn't handle the packets sent to multicast address properly...like those IPV6 multicast packets. I sent them to some strange places Now, I broadcast them to every hosts, I do not receive None buf_id anymore, and all hosts ping with each other Thank you very m

[pox-dev] manage events in Pox

Hi folk, I am very newbie to Pox and I need to develope a framework that implements the monitoring of SDN networks. To do this job I've integrated a monitoring application in my framework which send to Pox controller the alert of any suspected flow on the fly and suppose the controller can manage t

Hi, Murphy, I think I have send packet_out for every packet_in I just added more statements to print out logs, it shows that a lot of IPV6 multicast packets going through my network ...will that overwhelm the buffer? For the second possibility, do you mean I set the limitation to a smaller v

Re: [pox-dev] buffer_id is None?

I'm aware of two possibilities. The first is that your switch is out of buffer space/IDs. This can happen particularly if you are ignoring packet-ins in your controller. You may be better off sending a packet-out that references the buffer_id but has no actions; this way the switch will deall

[pox-dev] buffer_id is None?

Hi, all I'm developing some controller with POX, When I test it with mininet (--switch ovsk), I found that I will receive some packet_in which has a buffer_id with the value of None? Anyone had this problem before? obviously it is caused by my controller, I used other code to test, this type of

Re: [pox-dev] L2 and L3 calling from another

Thank you Murphy I have another question: I have got the switch MAC address, i.e., 00-00-00-00-0x, how can I convert it to dpid. I am working in l2_multi, while the switches array has something like [1: 00-00-00-00-01, 2: 00-00-00-00-02 ] is there a way to get the dpid number from switches array
