The network administrator configured R1 to authenticate Telnet connections based on Cisco ISE using TACACS+. ISE has been configured with an IP address of 192.168.1.5 and with a network device pointing toward R1(192.168.1.1) with a shared secret password of Cisco123.
The administrator has configured this on R1:
aaa new-model ! tacacs server ISE1 address ipv4 192.168.1.5 key Cisco123 ! aaa group server tacacs+ TAC-SERV server name ISE1 ! aaa authentication login telnet group TAC-SERV
