Description
The spanning-tree guard tc command is used to enable the TC Protect
function for a port. To disable the TC Protect of Spanning Tree 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 removing MAC
address entries, which may decrease the performance and stability of the
network. With the Protect of Spanning Tree function enabled, the switch will
drop TC-BPDUs.
