28.9.2 BPDU Filters
- <Structure of this section>
(1) Overview
On ports with the BPDU filter functionality applied, BPDU sending and reception stops. The BPDU filter functionality is applied to ports with PortFast set, for which a terminal is connected and loops are known not to occur.
(2) Notes on BPDU Filters
When the BPDU filter functionality is set for ports other than those with PortFast applied, because BPDU sending and reception are stopped, communication is cut off until a timer-based port status transition is completed.
