The spanning-tree tc-defend command is used to configure the TC Protect of
Spanning Tree globally. To return to the default configuration, please use no
spanning-tree tc-defend 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 removing MAC address entries, which may
decrease the performance and stability of the network.
