Cisco 2960 802.1x authentication fail

[computerdoctor995]

Physical switch version:

C2960 Boot Loader (C2960-HBOOT-M) Version 15.0(2r)EZ1, RELEASE SOFTWARE (fc1)
System image file is "flash:/c2960-lanbasek9-mz.150-2.SE5/c2960-lanbasek9-mz.150-2.SE5.bin"

The goal of this lab is only authenticated by the MAC address of the laptop.

Currently,I have a trouble as following and don't know what is this root cause .

Please give me a guide point. 

Thanks so much

I have a few questions:

1. What type of Radius server do you have?

2. Can you post a screen shot of your Radius AAA policies

3. Do you have the mac address entered in your Radius server

4. Provide the output from the following commands:

- show aaa servers

- show authentication session interface interface_name_number
