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

Usage Information By default, Dell Networking OS implements an optimized ush mechanism for RSTP. This implementation helps in
ushing 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 on this knob command to enable
ushing MAC addresses after receiving every topology change notication.
