set itself automatically as ERROR-PORT when receiving BPDU packets with

Example
Enable the Root Protect function for Gigabit Ethernet port 1/0/2:
T3700G-28TQ(config)#interface gigabitEthernet 1/0/2
T3700G-28TQ(config-if)#spanning-tree guard root
spanning-tree guard tc
Description
The spanning-tree guard tc command is used to enable the TC Protect of
Spanning Tree 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, you
can configure the number of TC-BPDUs in a required time, so as to avoid the
process of removing MAC addresses frequently.
Syntax
spanning-tree guard tc
no spanning-tree guard tc
