Question 4

The network administrator is tasked to configure R1 to authenticate telnet connections based on Cisco ISE using RADIUS. ISE has been configured with an IP address of 192.168.1.5 and with a network device pointing towards R1 (192.168.1.1) with a shared secret password of Cisco123. If ISE is down, the administrator should be able to connect using the local database with a username and password combination of admin/cisco123.

The administrator has configured the following on R1:

aaa new-model

!

username admin password cisco123

!

radius server ISE1

address ipv4 192.168.1.5

key Cisco123

!

aaa group server tacacs+ RAD-SERV

server name ISE1

!

aaa authentication login RAD-LOCAL group RAD-SERV
