Perle Systems Technical Notes
Many organizations are now creating policies that require that only strong passwords be used throughout the organization. The best way to enforce this is through the use of centralized authentication servers such as RADIUS or TACACS.

Password Strength Checking is supported in Perle Industrial Managed Switches with the PRO software feature set.
