I have a question about cascading a SG-200-26 and a Cisco SG-200-8 under 802.1x environment.
What we have and what's working fine:
We have a well configured SG-200-26 switch with a Radius Server (NPS) running on Windows 2008. Both are up'n running and on all Ports set to "Auto" it is not possible to get access with non allowed devices. Now we have to expand that switch with a smaller one, the Cisco SG-200-8. When I connect the 8-port switch to the large one and set that port to "forceAuthorize"and configure 802.1x settings as well the Radius settings an the small one to the same as on the large one, everything works fine. But that misses the goal, because when someone disconnects the small switch, any other device can get access to the LAN through that port because the port is set to "forceAutorize" instead of "Auto".
What's not working:
When I set the port on the large switch to "Auto" I'm not able to configure the small switch to put requests through to the large one. I tried to set it to "Supplicant" as well as to "Authenticator", both variants with enabled 802.1x and Radius and without.
Does someone has any ideas how to solve that? Any help is highly appreciated!
