4-7 config authen_login
Description
This command is used to configure a user-defined or default method list of authentication methods for
user login. The sequence of methods will affect the authentication result. For example, if the sequence
is TACACS+ first, then TACACS and local, when a user trys to login, the authentication request will be
sent to the first server host in the TACACS+ built-in server group. If the first server host in the
TACACS+ group is missing, the authentication request will be sent to the second server host in the
TACACS+ group, and so on. If all server hosts in the TACACS+ group are missing, the authentication
request will be sent to the first server host in the TACACS group. If all server hosts in a TACACS
group are missing, the local account database in the device is used to authenticate this user. When a
user logs in to the device successfully while using methods like
TACACS/XTACACS/TACACS+/RADIUS built-in or user-defined server groups or none, the "user"
privilege level is assigned only. If a user wants to get admin privilege level, the user must use the
"enable admin" command to promote his privilege level. But when the local method is used, the
privilege level will depend on this account privilege level stored in the local device.
