Yes i did follow the guide - in my home lab i get it to work. I wanted to integrate this in the business network - but with the same config i didn't get it to work.
The setup is like this:
The Switch has configured a mgmt - VLAN (IP 172.31.20.20).
On this switch I configured these settings: (192.168.99.5 is the ip of the clearpass appliance)
radius-server host 192.168.99.5 key "Secret"
radius-server host 192.168.99.5 dyn-authorization
radius-server host 192.168.99.5 time-window 0
aaa authentication port-access chap-radius
aaa authentication captive-portal enable
aaa port-access mac-based 8
Then the captive portal opens with some parameters (mac, ip, timestamp) in the url.
In the office i get the captive portal, but without these parameters. Then I want to login and the message appears that not the required parameters were found.
The switch at home and office is exact the same type and firmware. The only difference is that in the office the routing is much more complex - but all ports needed are open. I can also see the applied ACL on the switch.
Are there some requirements that have to been met on switch side so that everything works?
