Information
By default FTOS implements an optimized flush mechanism for RSTP. This 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, this knob command can be turned
on to enable flushing MAC addresses upon receiving every topology change notification.
