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!

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,
