There are two commands you can use to do this, depending on the release you have of the

Cisco IOS software:

•

enable secret password (which is a very secure, encrypted password).

•

enable password (which is a less secure, or nonencrypted, password).

The enable secret password is available in Cisco IOS Release 10.2(3) or later. The enable

secret password is not available before Release 10.2(3). The enable password is available

in all releases. You must enter the correct password to gain access to privileged-level

commands.

On systems running Release 10.2(3) or later, the enable secret password is used. when you

are running from the boot ROM, the enable password might be used depending on your

ROM level.

The passwords should be different for maximum security. If you enter the same password

for both during the setup script, the system will accept it, but you will receive a warning

message indicating that you should enter a different password.

An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric

characters; an enable password can contain any number of uppercase and lowercase

alphanumeric characters. In both cases, a number cannot be the first character. Spaces are

also valid password characters; for example, "two words" is a valid password. Leading

spaces are ignored; trailing spaces are recognized.

If you lose or forget your enable password, see the section "Recovering a Lost Enable

Password" in the chapter "Maintaining the Cisco 2500 Series Access Server."
