Usage Information By default, Dell Networking OS 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.
