Enabling user password aging
The password aging feature enforces updates of all user passwords each half of the year. After
180 days, the CLI automatically prompts users to change their passwords when they attempt to
sign on the Brocade Virtual ADX. By default, password aging is disabled.
To enable the password aging feature, enter the following command.
Virtual ADX(config)# enable user password-aging
Syntax: [no] enable user password-aging
When password aging is enabled, the Brocade Virtual ADX records the system time when each user
password was configured or last changed. The output of the show running-config command
displays the time, as indicated by set-time time.
Example
Virtual ADX(config)# show running-config
! Building configuration
....
telnet server
username admin password .....
username admin set-time 1374235760
....
A username set-time configuration is removed when:
• The username and password is deleted from the configuration
• The username password expires
When a username set-time configuration is removed, it no longer appears in the show
running-config output.
NOTE
If a username does not have an assigned password, the username will not have a set-time
configuration.
Configuring password history
By default, the Brocade Virtual ADX stores the last five user passwords for each user. When
changing a user password, the user cannot use any of the five previously configured passwords.
For security purposes, you can configure the Brocade Virtual ADX to store up to 15 passwords for
each user, so that users do not use the same password multiple times. If a user attempts to use a
password that is stored, the system prompts the user to choose a different password.
For example, to configure a password history for 15 passwords, enter the following command.
Virtual ADX(config)# enable user password-history 15
Syntax: [no] enable user password-history password_history
The password_history variable specifies the number of stored user passwords. Enter an integer
from 1 to 15. The default is 5.
