Usage Information By default, the system implements an optimized ush mechanism for PVST+. This implementation helps in ushing
the MAC addresses only when necessary (and less often) allowing for faster convergence during topology
changes. However, if a standards-based ush mechanism is needed, you can turn this knob command on to enable
ushing MAC addresses after receiving every topology change notication.
