Password Control Configuration Operations

Introduction to Password Control Configuration

The password control feature is designed to manage the following passwords:
Telnet passwords: passwords for logging into the switch through Telnet.
SSH passwords: passwords for logging into the switch through SSH.
FTP passwords: passwords for logging into the switch through FTP.
Super passwords: passwords used by the users who have logged into the switch and are changing
from a lower privilege level to a higher privilege level.
Password control provides the following functions:

Description
Password aging time setting: Users can set the aging
time for their passwords. If a password ages out, its user
must change it, otherwise the user cannot log into the
device.
Password change: After a password ages out, the user
can change it when logging into the device.
Alert before password expiration: Users can set their
respective alert time. If a user logs into the system when
the password is about to age out (that is, the remaining
usable time of the password is no more than the set alert
time), the switch will alert the user to the forthcoming
expiration and prompts the user to change the password
as soon as possible.
This function is used to limit the minimum length of the
passwords. A user can successfully configure a
password only when the password is not shorter than its
minimum length.
History password recording function: The password
configured and once used by a user is called a history
(old) password. The switch is able to record the user
history password. Users cannot successfully replace
their passwords with history passwords.
History password protection function: History passwords
are saved in a readable file in the Flash memory, so they
will not be lost when the switch reboots.
