• If no BPDU is received from a remote device, loop guard places the port in a Loop-Inconsistent Blocking state
and no traffic is forwarded on the port.

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.
