Information

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals.

If the network device allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

Solution

Go to Device >> Setup >> Management
In the 'Minimum Password Complexity' window, select the 'Edit' icon (the gear symbol in the upper-right corner of the pane).
In the 'Prevent Password Reuse Limit' field, enter '5'.
Check the 'Enabled' box, then select 'OK'.
Commit changes by selecting 'Commit' in the upper-right corner of the screen.
Select 'OK' when the confirmation dialog appears.
