Password policies
The password policies described in this section apply to the local switch user database only.
Configured password policies (and all user account attribute and password state information) are
synchronized across CPs and remain unchanged after an HA failover. Password policies can also be
manually distributed across the fabric (see

Following is a list of the configurable password policies:
•
Password strength
•
Password history
•
Password expiration
•
Account lockout
All password policies are enforced during logins to the standby CP. However, you may observe that
the password enforcement behavior on the standby CP is inconsistent with prior login activity
because password state information from the active CP is automatically synchronized with the
standby CP, thereby overwriting any password state information that was previously stored there.
Also, password changes are not permitted on the standby CP.

Password strength policy
The password strength policy is enforced across all user accounts, and enforces a set of format
rules to which new passwords must adhere. The password strength policy is enforced only when a
new password is defined. The total of the other password strength policy parameters (lowercase,
uppercase, digits, and punctuation) must be less than or equal to the value of the MinLength
parameter.
