Usage By default, the system implements an optimized flush mechanism for RSTP. This
Information 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.
