Setting a Console Password

By default, there is no console password. To set a console password:

1. Make sure that you know the enable password for the system.

   If you need to reset the enable password, see Privilege Levels .

2. Access Privileged Exec mode, and enter the enable password if prompted.
3. Access Global Configuration mode.
4. Access Line Configuration mode.

   host1(config)#line console 0

5. Enable password checking at login.

   host1(config-line)#login

6. Specify a password.

   host1(config-line)#password 7 dq]XG`,%N"SS7d}o)_?Y

line

• Use to specify the vty lines or the console.
• Example

  host1(config)#line vty 1 4

• Use the no version to remove a vty line or a range of lines from your configuration; users will not be able to run Telnet, SSH, or FTP to lines that you remove. When you remove a vty line, the system removes all lines above that line. For example, no line vty 6 causes the system to remove lines 6 through 29. You cannot remove lines 0 through 4.
• See line.

login

• Use to enable password checking at login.
• The default setting is to enable a password.
• Example

  host1(config)#line vty 1 4

  host1(config-line)#login

• Use the no version to disable password checking and allow access without a password.
• See login.

password

• Use to specify a password on the console, a line, or a range of lines.
• If you enable password checking, but do not configure a password, the system will not allow you to access virtual terminals.
• Use the following keywords to specify the type of password you will enter:
  • 0 (zero)—Unencrypted password
  • 5—Secret
  • 7—Encrypted password

Note: To use an encrypted password or a secret, you must follow the procedure in Setting Basic Password Parameters to obtain the encrypted password or secret. You cannot create your own encrypted password or secret; you must use a system-generated password or secret.

• Example 1 (unencrypted password)

  host1(config-line)#password 0 mypassword

• Example 2 (secret)

  host1(config-line)#password 5 bcA";+1aeJD8)/[1ZDP6

• Example 3 (encrypted password)

  host1(config-line)#password 7 dq]XG`,%N"SS7d}o)_?Y

• Use the no version to remove the password. By default, no password is specified.
• See password.
