Enable Passwords
You set the enable passwords from global configuration mode.
Router(config)#enable ?
last-resort Define enable action if no TACACS servers
respond
password Assign the privileged level password
secret Assign the privileged level secret
use-tacacs Use TACACS to check enable passwords
Last-resort Is used if you set up authentication through a tacacs server
and it is not available. This will allow the administrator to still enter the
router. However, it is not used if the tacacs server is working.
Password Is used to set the enable password on older, pre-10.3 systems.
Not used if an enable secret is set.
Secret Is the newer, encrypted password. Overrides the enable password
if set.
Use-tacacs Tells the router to authenticate through a tacacs server. This
is convenient if you have dozens or even hundreds of routers. How would
you like to change the password on 200 routers? The tacacs server allows
you to only have to change the password once.
Router(config)#enable secret todd
Router(config)#enable password todd
The enable password you have chosen is the same as your
enable secret. This is not recommended. Re-enter the
enable password.
If you try and set the enable secret and enable passwords to be the same, it will
give you a nice, polite warning the first time, but if you type the same password
again it will accept it. However, now neither password will work. If you don’t
have older legacy routers, don’t bother to use the enable password.
User-mode passwords are assigned by using the line command.
Router(config)#line ?
First Line number
aux Auxiliary line
