Hi KK, I finally got this to work, thanks for the instructions. I basically downloaded the noxcore+openroads+openflow git's to the PC Engine itself to overcome any compatibility problems and compiles AP-Subagents from there. Now, i can listen to SNMP traps, get/set too at the controller. I also traced SNMP messages between AP and controller when the mobile node (my laptop) connects to the AP i see the following snmp messages at the controller side (see attached image "snmp"). Am facing a little problem on the controller side. The problem is, when the AP connects to the controller i see too many packet-ins at the controller's side (about 1000 packets/sec).see attached image for the controller and AP terminals. I received 106800+ packet-ins in less than 2 minutes. my topology is: Controller - - - - - - (regular 8 ports switch)* - - - - - Openflow enabled AP - - - - - mobile node
* the switch is not Openflow enabled. note that i used the same switch without problems but the AP was WRT54G instead of PC Engine.

A concise description would be the following: 1) Copy the files in config-files to where they are needed. These are configurations for snmpd and snmp-trapd in Linux, plus the MIB files needed. Instructions are no different from standard SNMP installation in Linux. 2) Compile the subagents in the ap-subagents directory. These do not need snmp_message.hh. The binaries are SNMP agentx, which should be invoked when the AP starts up. 3) Finally the NOX components in found in the NOX directory. This should be added to the netapps. 4) In the zaku branch of NOX, you will find traphandler.py which should be registered in snmptrapd.conf to handle traps. With these in place, you should be able to listen in on SNMP traps and SNMP get/set in NOX. Hope this will get you going.

In OpenRoads:SNMP page, the instructions are clear about compiling the code in openroads-wifi-snmp/server & openroads-wifi-snmp/ap_subagents/ directories to create the following files ( wifi_subagent, trap_subagent and keepalive_subagent) to be transferred to the AP's later. To do that i need snmp_message.hh and without it, i have no files. The question now is: will the setup procedure change in OpenRoads:SNMP wiki page when changing to of1.0-noxdestiny branch?

The snmp_executor is not needed anymore in that branch. There was some changes made to NOX and therefore the changes were made when we transited from OpenFlow v0.8.9 to v1.0.

The instructions for OpenRoads are for the PC Engines. OpenWRT supports snmp (you can install the net-snmp package on top of the given binaries or build a custom image that contains it). The main issue though is that the openroads-specific snmp extensions need to be ported to openwrt, which we haven't tried so far. These are typically compiled against the snmp-agent code, so you need to make sure that you set things in your cross-compiler accordingly. Please keep me posted in case you go forward and try to incorporate the SNMP extensions to the openwrt build. Thanks, Yiannis On Fri, Jun 24, 2011 at 10:16 AM, kk yap <yap...@stanford.edu> wrote: Hi Landy, This question would be Openwrt specific. The instructions for OpenRoads (OpenFlow Wireless) are for the PCEngine based APs. Yiannis might know the Openwrt stuff best here. From what I know, the short answer is yes. And the longer answer is you should expect some work to get there.

I have 3 WRT54GL openflow-enabled AP's, and x86 32-bit controller. The AP's and controller are working properly. Am a bit confused about instructions on THIS PAGE. Which one is the development machine (is it my controller?). Also, what is the server, (is it the controller too?). Is it possible to add snmp to these AP's or i should get PC engines instead?
