Example: Enabling ChPass with a Blank Password Change

In the following example, the ChPass feature is enabled, and a blank password change is accomplished using
the SSH Keyboard Interactive Authentication method. A TACACS+ access control server (ACS) is used as
the back-end AAA server.
Device1# ssh -l cisco 10.1.1.3
Password:
Old Password: cisco
New Password: cisco123
Re-enter New password: cisco123
Device2> exit
[Connection to 10.1.1.3 closed by foreign host]
