Authenticate my switch using ISE server

Hello everyone,

I am trying to configure my switch so everyone who has an account on my AD can log in using ISE authentification server. I use DMVPN to my spokes with the Hub. All my spoke routers and hub devices are well configured and can use my ISE to log except my switches behind my spokes routers. Here is the configuration in one switch: 

SPOKE-3-CORE#sh run

% Authentication failed

But I used to have that on other equipment I used to log as well. just to let you know.


Got to ask, is the ISE then compatible with this make of switch?

For that, I don't know. I am using a Cisco IOL virtual switch.

I found the error and fixed it. the issue was the bandwidth on the tunnel. 

Changed the source

interface to ethernet 0/0

and under the tunnel interface, I changed the bandwidth to 85k

interface tunnel 10
bandwidth 85000
