RSTP provides different functions in different scenarios. Which of the following statements Is false?
A.
After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period
B.
The role of the designated port that is enabled with root protection cannot be changed
C.
If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation
D.
When the designated port enabled with root protection receives optimal RST BPDUs, the port enters the Discarding state and does not forward packets. If the port does not receive optimal RST BPDUs within a certain period of time, the port will automatically restore to the Forwarding state
Root protection ensures that a designated port does not become a root port by discarding superior BPDUs. However, if superior BPDUs are no longer received, the port can return to its original forwarding state, meaning its role can change. This makes option B incorrect, while the other options correctly describe RSTP behavior .
