Usage
Information
By default, FTOS implements an optimized flush mechanism for RSTP. This implementation
helps in flushing MAC addresses only when necessary (and less often), allowing for faster
convergence during topology changes. However, if a standards-based flush mechanism is
needed, you can turn on this knob command to enable flushing MAC addresses after receiving
every topology change notification.
