Chapter 6 Configuring the Router
Performing the Initial Configuration on the Router
Configuring the Enable and Enable Secret Passwords
To provide an additional layer of security, particularly for passwords that cross the network or are stored
on a TFTP server, you can use either the
enable password
command or
enable secret
command. Both
commands accomplish the same thing—they allow you to establish an encrypted password that users
must enter to access privileged EXEC (enable) mode.
We recommend that you use the
enable secret
command because it uses an improved encryption
algorithm. Use the
enable password
command only if you boot an older image of the Cisco IOS
software or if you boot older boot ROMs that do not recognize the
enable secret
command.
For more information, see the “Configuring Passwords and Privileges” chapter in the
Cisco IOS Security
Configuration Guide
. Also see the
Cisco IOS Password Encryption Facts
tech note and the
Improving
Security on Cisco Routers
tech note.
Restrictions
If you configure the
enable secret
command, it takes precedence over the
enable password
command;
the two commands cannot be in effect simultaneously.
