BLADE OS 5.1 Release Notes
Strong Password Expiration
If you configure a Strong Password with automatic expiration, the password might not expire if the system date and time is not configured first. Use of a Network Time Protocol (NTP) server resolves this issue.
Solution: When you configure a strong password with automatic expiration, first configure the system time and date for the switch.
