[mininet-discuss] Using setARP() with setMAC() && setIP()

Hello,
I'm looking to statically configure IP and MAC on host interfaces and then set static ARP entries on each host. 
Have tried multiple variations of using h.setIP(), h.setMAC(), and setARP(), but manual ARP entries will not work after manually setting the MAC on the interface.  I've tried h.cmd() as well to config ARP entries.  If I only configure a static IP (with default MAC), the ARP entries work fine...clearly, that is unacceptable though :).  After adding the static IP+MAC, the ARP entries no longer work...have also tried placing net.start() in different locations to see if that helps...no dice there.

Been at this for hours, so any help would be greatly appreciated :)

I've taken a look at this and doesn't seem to be helping:https://mailman.stanford.edu/pipermail/mininet-discuss/2013-October/003258.html


Code here showing various things with some commented out as well...
if __name__ == '__main__':    setLogLevel( 'info' )    topo = MyTopo()    net = Mininet(topo=topo, switch=UserSwitch, controller=RemoteController)    #net.start()    h1, h2, h3 = net.hosts    hosts = [h1,h2,h3]    ip_mac = {'10.0.0.10':'00:00:00:00:00:10','10.0.0.11':'00:00:00:00:00:11','10.0.0.12':'00:00:00:00:00:12'}    c=10
    net.start()    for h in hosts:      ip, mac = "10.0.0."+str(c), "00:00:00:00:00:"+str(c)      #h.setIP("10.0.0."+str(c)+"/24")      #h.setMAC("00:00:00:00:00:"+str(c))      h.setIP(ip+"/24")      h.setMAC(mac)      h.setARP('10.0.0.8', "00:00:00:00:00:02")      '''      for cip in ip_mac.keys():         if not cip == ip:          h.setARP(cip,ip_mac[cip])          print cip + ' ' + ip_mac[cip]      '''       c+=1        CLI(net)    #h2.setARP('10.0.0.8', "00:00:00:00:00:02")    #h2.cmd('arp -i h1-eth0 -s 1.1.1.1 00:00:00:00:00:12')            net.stop()
Thanks,
Jason
