is there any special settings i have to do on a cisco router if i want to get 802.1x working on a cisco router on a stick everything works on the network except that when i do test aaa radius on the cisco wlc i get radius server unresponsive the wlc can ping the server and it persists with or without windows firewall there is no acl's on the cisco router and dhcp relay is configured and working with ip help-addresses pointing at the dhcp server i just cant seem to get it to work i had it working when my pfsese firewall was doing router on a stick but now i am using my cisco 2901 for speed reasons
What version of software?
Can ping the server from which interface? (maybe not the same interface the radius is originated from)
You can do debugs on WLC and packet captures on router to see what's happening.
WLC is 2504
version of software is wlc 184.108.40.206 the software of the router Version 15.7(3)M5 and the network policy server is windows server 2019
the wlc can ping both its default gateway the default gateway server and the server itself
can u be nice and get me the commands i need to run?
"show interface summary" to get the name of the client interface
ping <server ip> "client interface name"
debug aaa all
As the server runs Windows you can use Wireshark for packet capture on server side: https://www.wireshark.org/#download
Those are all WLC commands.
You can also do packet capture on the router: https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-embedded-packet-capture/116045-productconfig-epc-00.html#anc10
