Disabling the aux port.
The no exec command disables all EXEC sessions to the router via that port. Do not issue this command on the console port of the router because it will disallow all exec sessions to the router's console port.
Encrypting All Passwords on the Router
By default, only the enable secret password is encrypted. To encrypt all other passwords configured on the router, issue the following command in global configuration mode:
Router(config)# service password-encryption
In Figure 3.6
, the administrator is encrypting all the passwords except the enable secret password.
