ISE RADIUS and Nexus 9k

emrglr
Level 1
Level 1

I have Nexus 9k connected to an ISE server for login authentication and the login goes through and I am successfully logged into the 9k however when i try to log in same username/wrong password login goes successfully anyway. So i think ISE not checking the password. What am I missing?

--------------------------------------------

radius-server key 7 "fewhg"
radius-server host 172.16.5.238 authentication accounting
aaa group server radius ISE
server 172.16.5.238
source-interface Vlan5

aaa authentication login default group ISE ISE

I am suspecting misconfiguration in authentication policy on ISE. Could you check if option selected in "If Auth fails" is "Continue". It should be "Reject".
