Tutu,

To break down what you're seeing in a couple steps.

 

1. Event 5434 Endpoint conducted several failed authentications of the same scenario

Answer:  This happens when a device triggers ISE's Anomalous Client Suppression function.  I think by default it triggers when a device (mac address) with an identity, fail for the same reason 5 times within 15 minutes.  Instead of spending cycles processing the request, ISE just applies the last result that was applied to the device.  What that means is if there is an issue, even if you fix, the device won't authenticate differently for 1 hour.  To get around this in Radius Live Logs, find the device, and click the "Star" next to the device id, then click "Bypass suppression filtering for 1 hour".

 

2. Failure Reason 12117 EAP-FAST inner method finished with failure
Resolution Verify that the client supplied the correct credentials, such as username and password. Verify that the client's supplicant is properly configured to use an inner method protocol that is supported by ISE. Check the previous 'Steps' in the Log for this EAP-MD5 conversation for any message that might hint why the inner method failed.
Root cause EAP-FAST inner method finished with failure.
Username anonymous

Answer:  I haven't used EAP-FAST in a while, but I think the inner method is PEAP authentication or Username and Password.  ISE is telling us that the username is anonymous.  Which I believe means that no username is being provided.  ISE even tells us a resolution, Verify that the client supplied the correct credentials, such as username and password.

 

3.15041 Evaluating Identity Policy
15013 Selected Identity Source - Guest Users
24631 Looking up User in Internal Guests IDStore
22059 The advanced option that is configured for process failure is used
22062 The 'Drop' advanced option is configured in case of a failed authentication request

 

Answer: Looks like you're trying to do guest authentication from a wired connection?  Generally for Guest authentication, a username won't be supplied.  By default the AuthC policy of your policy set will "Drop" the authentication on a failed authentication request, or if the identity isn't found in the selected identity store, which we can see is "Guest Users".  For guest authentication, you need to set the AuthC condition for user not found to "Continue".

 

Hope this helps!

This is beyond what most people here on these forums can assist with. If this were a Cisco IP phone, then you'd be having an issue because you didn't reply with a Cisco AVPair that puts that device into the Voice VLAN.  

Does you switch port have only one VLAN, or do you have a Data VLAN and a Voice VLAN? (I didn't think Voice VLAN tagging works on non-Cisco devices - but perhaps that;s your issue). If so, then you need to edit your Authorization Profile and tick the box called 'Voice Domain Permission.

I have edited the Authorization profile and have checked the box for Voice Domain permission,

I do not know where it is getting the ip from. as that is not the ip range for voice vlan. its .32
