Usage Information By default, the system implements an optimized flush mechanism for PVST+. This
implementation helps in flushing the 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 this knob command on
to enable flushing MAC addresses after receiving every topology change
notification.
