function, please use no spanning-tree guard tc command. A switch removes
MAC address entries upon receiving TC-BPDUs. If a malicious user
continuously sends TC-BPDUs to a switch, the switch will be busy with

can configure the number of TC-BPDUs in a required time, so as to avoid the
process of removing MAC addresses frequently.
