NAC (ExtremeControl) - Don't see End-Systems Connected on my ERS Switch

[kevin_phi]

Hello every one, 

I tried to setup Extreme Control on my XMC in order to see what’s connected on our network.

The NAC appliance has been added to my XMC.

My Switch (ERS4900 Series) has been added in “Switches” on Access Control Tab. 

There are two IP Phones connected on the port 1 and 2 but I don’t see these devices in  “end-systems” on Access Control.

Does someone know what I have to do exactly (procedure?), maybe I missed something in my configuration...

I only need to use Access Control in “listen” mode, no authentication or security… only be able to see what’s connnected on my network in a first time.

It would be helpful if someone already have experience(s) about this.

Because the radius rejects the the request from switch, it looks like there is a config missmatch.

if you have already checked the shared secret, Is your NAC-Config enforced to the control-engine?

This is one of the most mistakes...

Hi Tomasz, 

Yes correct. I would like to see the end-devices in NAC.

My NAC is enabled in my XMC but not in use. So that’s why I don’t know if the issue come from NAC/XMC or my switch or both.

Will get a look on your documentation and thanks for your feedback.

After seeing a lot of Extreme TechTalks, Videos and e-learning on Dojo Web portal, I thought  I understood that it will a quick and easy configuration but seems to be not the case.

Hi Kevin,

I don’t remember much of AAA config on ERS, but don’t you need non-EAP settings (in your output it’s 0.0.0.0) if MAC Auth is required? Assuming MAC Auth as you say you’d like to just see devices in NAC (no real authentication occurring?).

Hope that helps,

Tomasz

Yes but I don’t find what can cause my issue. 

I only need the use my NAC in listen mode, on paper it’s a quick and light config 

In all Extreme TechTalks, Videos or documentation it’s just said to add the NAC appliance in XMC and the switch that you need to “listen”…. 

And the support are not able to help me, it's an endless loop...
