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.
