password : Password to be set. The password must be in plain text if you specify the simple keyword in
the set authentication password command. If you specify the cipher keyword, the password can be
in either cipher text or plain text, as described in the following.
z
When you enter the password in plain text containing no more than 16 characters (such as 123),
the system converts the password to the corresponding 24-character encrypted password.
z
When you enter the password in cipher text containing 24 characters, make sure you are aware of
the corresponding password in plaintext. For example, the plain text “123456” corresponds to the
cipher text “OUM!K%F<+$[Q=^Q`MAF4<1!!”.
Description
Use the set authentication password command to set the local password.
Use the undo set authentication password command to remove the local password.
Note that only plain text passwords are expected when users are authenticated.
By default, password authentication is performed when a user logs in through a modem or Telnet. If no
password is set, the user cannot establish a connection with the switch.
