Usage Information By default, Dell Networking OS implements an optimized flush mechanism for MSTP.
This mechanism 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, this knob command can be turned on to
enable flushing MAC addresses after receiving every topology change notification.
