Usage guidelines
If prohibited permanently, a user can log in only after you remove the user from the password control
blacklist.
If prohibited temporarily, a user can log in again after the lock time elapses or an administrator removes
the user from the password control blacklist.
If not prohibited to log in, a user is removed from the password control blacklist as long as the user logs
in successfully or after the blacklist aging time (1 minute) elapses.
Examples
# Set the maximum number of login attempts to 4 and permanently prohibit a user from logging in if the
user fails to log in after four attempts.
<Sysname> system-view
[Sysname] password-control login-attempt 4 exceed lock
Later, if a user tries to log in but fails four times, you can find it in the password control blacklist with its
status changed from unlock to lock:
[Sysname] display password-control blacklist
Username: test
IP: 192.168.44.1 Login failed times: 4 Lock flag: lock
Total 1 blacklist item(s) matched. 1 listed.
The user can no longer log in.
# Set the maximum number of login attempts to 2 and prohibit a user from logging in within 3 minutes
if the user fails to log in after two attempts.
