[pox-dev] FW: Build MAC list

[AMER]

Hello,
 
I tried the following:
 
pox.py forwarding.l2_multi openflow.discovery proto.dhcpd --network=10.1.1.0/24 --ip=10.0.0.4 --first=10

in l2_multi,  from pox.lib.packet.dhcp import *
under Switch() class I added
core.DHCPD.addListenerByName('DHCPLease', _H_hate_)def _H_hate_ (self, event):
    macmap[event.connection.dpid] = event.host_mac
    print "DHCP"
 
in mininet CLI
>h4 dhclient -v

Thank youThis means I should ping each host in the network to get the packets.I want something automatic like openflow discovery to discover the clients. I have another question:What does DHCP request message has (i.e., attributes)? In POX not in general.

Hi Amer,


I am not too sure if I understand your question,but to my current learning, all the above fields can be collected as in_port.src (mac ID), event.dpid (switch connection) and event.port( inport).

Cheers!
Durga

Hello,



I want to collect MAC addresses of each host in the network and switch they connect to and port number.

I think about DHCP and openflow discovery, but I do not know how to combine them.





Best regards,

Amer
