ARP vs Openflow

[Iain_Young]

Hi Guys,

I am experimenting with a 5406zl with openflow firmware. The setup is very simple. One openflow instance, with one vlan in it (24), and 3 untagged ports (A2,A4,A6). Mangement/Native vlan is 192.168.39.0/24. ip routing is enabled

When openflow is disabled, everything is fine Hosts within the vlan can ping and arp each other just fine, However cthey annot arp the .1 (which the 5406zl is hosting), and it seems that the 5406zl cannot arp the hosts either.

Here is the appropriate parts of the 5406 config:

vlan 1
   name "DEFAULT_VLAN"
   no untagged A2,A4,A6
   untagged A1,A3,A5,A7-A24,B1-B24
   ip address 192.168.39.253 255.255.255.0
   exit
vlan 24
   name "VLAN24"
   untagged A2,A4,A6
   ip address 172.17.248.1 255.255.255.0
   ip local-proxy-arp
   exit

openflow
   enable
   controller-id 65 ip 192.168.39.76 controller-interface vlan 1
   instance "24"
      member vlan 24
      controller-id 65
      enable
      exit
   exit

The controller is running floodlight, but beacon has also been tried. I first thought it was a proxy ARP issue (I was trying from 192.168.39.0/24), so installed the proxyARP module to floodlight, but to no avail. Even adding the MAC for the switch manually on the hosts within 172.17.248.0/24 doesn't help (Guess the arp still doesnt work in the other direction, although it also suggests the switch itself (as 172.17.248.1) doesnt see the packet coming from the node)

Other things I have tried are ip local-proxy-arp, and proxy-arp on the vlan24 interface, the aggregate openflow instance, and K.15.12.0006 firmware

Anyone else who is experimenting with openflow see similiar ? Anyone know what I may have missed ? Or is this a limitation with the openflow support in the 5406 ?

Best Regards
