Usage
Information
By default, Dell Networking OS implements an optimized flush mechanism for RSTP. This implementation
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, you can turn on this
knob command to enable flushing MAC addresses after receiving every topology change notification.
