Usage
Information
By default, FTOS implements an optimized flush mechanism for PVST+. This 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, you can
turn this knob command on to enable flushing MAC addresses after receiving every topology
change notification.
