Do you have a local username and password configured on the switch or router?

 

Yes I have, username xxx privilege 15 secret xxx. But that doesn t work.

 

ip domain-name xxx      

crypto key generate rsa        

ip ssh time-out 120            

ip ssh authentication-retries 3

ip ssh version 2

 

aaa new-model

aaa group server radius ISE

server xxx.xxx.xxx.xx

server xxx.xxx.xxx.xx

 aaa authentication login VTY group ISE local

aaa authorization exec VTY group ISE local if-authenticated

aaa accounting exec default start-stop group ISE          

 

radius-server host xxx.xxx.xxx.xx key 0 xxx

radius-server host xxx.xxx.xxx.xx key 0 xxx

 

line vty 0 15

transport input ssh

login authentication VTY

authorization exec VTY    

this is my configuration on swith. I have policy on ISE , and I login over ssh with my admin domain username and password. When ISE is not on network, I cannot login on switch. Maybe is problem with this command:

aaa authentication login VTY group ISE local ?

 

Hi

Heres a working one of mine when  ACS or ISE are not working it still authenticates off local DB in device , you must have enable after local too
