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
expiration and prompts the user to change the password
as soon as possible.
This function is used to limit the minimum length of the
of
passwords. A user ca
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: Histo
are saved in a readable file in the Flash memory, so they
will not be lost when the switch reboots.
