Information
By default, the system 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.
