I have an EPON OLT it is connected with Cisco switch on eth-23. I can see it's MAC address on bridge FDB of switch. And Cisco switch is directly connected with CCR-1009. Whole network is look like this..
CCR-1009(DUDE Installed)-------->Cisco Swicth(eth-23)--------->EPON OLT(ALL Custoners ONU).

So I want to monitor EPON OLT with dude server, but I can't get it done. By default at auto discovery Dude doesn't see My EPON OLT and also not see all devices connected to Cisco switch. Dude got info about my Cisco switch but not for all devices connected to it.
I want to monitor EPON OLT and all customer ONU's monitoring.

Can somebody help me about this. I am trying this from longtime, please I need your help ! 

ps. Moved your post to a new topic as it's not really related to probe topic.
