Cisco encrypt password
From D3xt3r01.tk
WHAT
If you ever add usernames on a cisco .. you want them to be encrypted ( and not be viewable at any "show running-config" ) .. here's how
HOW
Router#configure terminal
Router(config)#service password-encryption
Router(config)#username newuser privilege 15 secret justapassword
Don't use non-encrypted or just "password" (it can be reversed). Enjoy.
