Description
The password aging function has
the following sub-functions:
Password aging time setting:
■
users can set the aging time for
their passwords. If a password
ages out, its user must update it,
otherwise the user cannot log in
the switch.
Password update: after a
■
password ages out, the user can
update it when logging in the
switch.
Alert before password expiration:
■
users can set their respective alert
times. When a user logs in the
system and 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 alerts the
user to the forthcoming
expiration and prompt the user
to update 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 length of
the password is not shorter than its
minimum length.
