Can someone please explain the following configuration on Cisco router? In particular what login authentication line does? Also what is the effect of adding both login authentication line and login tacacs?
Can an expert please tell me why I can't add login tacacs on GNS3 routers? I can only add login local.
line vty 0 4
exec-timeout 60 0
timeout login response 90
password 7 12518596 login authentication line
