Usage
Information
By default, Dell EMC 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.
