Hello.. I want to clear all the data that my switches stored when they disconnect. is there any way to track disconnection of switches and host? Any idea? Thanks Muhammad

Re: [pox-dev] ARP request

Hello, You can use: 1. Broadcast something as following If match.dl_type = packet.ARP : match.src=Packet.src match.dst=packet.dst action = FLOOD 2. Set the ARP in each for each hosts using new version of mininet check this post in mininet archive https://mailman.stanford.edu/p

Re: [pox-dev] [mininet-discuss] host unreachable

https://openflow.stanford.edu/display/ONL/POX+Wiki#POXWiki-InvokingPOX you have to run pox with a component like "./pox.py samples.pretty_log forwarding.l2_learning" I'm assuming you didn't do that On Wed, Nov 13, 2013 at 10:42 AM, farshad tajedin wrote: > hi > when i run mininet by like

Re: [pox-dev] get_path info for two hosts

I guess that depends on what "host" means to you. Recapping my previous message, l2_multi maintains: * mapping between ethernet addresses and Switches * paths between pairs of Switches So if "host" means "observed Ethernet address", then yes. If "host" means "IP address", then no, it can't do it

Re: [pox-dev] host unreachable

Also, to add to what Sulabh advised, It would be nice if you can provide us with more info on what topology you have implemented. Apart from that, if you are using mininet vm , wireshark is inbuilt and you can fire it up, using ' sudo wireshark & 'that should help you see the packets and understan

Re: [pox-dev] get_path info for two hosts

Hello, Thank you I want to get the network path between two hosts. Is this possible in l2_multi. For switches what I should use, their names or what? Regards, On ١٣‏/١١‏/٢٠١٣, at ١٠:٥٦ م, Murphy McCauley wrote: > IP addresses don't mean anything to l2_multi. If they did, it'd be l3_multi. >

I have implemented this code to handle ARP.. is it ok ? I am not sure about that.. need your comments please a= packet.find('arp') if a: if a.prototype == arp.PROTO_TYPE_IP: if a.hwtype == arp.HW_TYPE_ETHERNET: if a.protosrc != 0:

Re: [pox-dev] get_path info for two hosts

IP addresses don't mean anything to l2_multi. If they did, it'd be l3_multi. :) l2_multi works on L2 (Ethernet) addresses. Even so, the path finding functions find paths between *switches*, not addresses. Specifically, they find paths between l2_multi's Switch objects (I think if you'd print

Re: [pox-dev] ARP request

Durga is spot on, but I'll throw in another couple things you might look at: forwarding.l3_learning handles ARP proto.arp_helper attempts to make it easier to work with ARP (Oh, and misc.arp_responder has moved to proto.arp_responder in newer versions.) -- Murphy On Nov 13, 2013, at 2:06 AM, dur

Re: [pox-dev] Openflow 1.3

Not quite. POX supports OpenFlow 1.0 with Nicira extensions. Lots of OpenFlow 1.3 features are derived from the Nicira extensions so there's lots of overlap in the featuresets, but the two aren't the same thing. If your switch supports Nicira extensions and the feature you need is available a

You can start pox with layer 2 learning algorithm. Try this: ./pox.py forwarding.l2_learning On Wed, Nov 13, 2013 at 1:42 PM, farshad tajedin wrote: > hi > when i run mininet by like "sudo mn --controller remote" and run > ./pox.py and ping h2 from h1 i get destination host unreachable, while
