26.20 spanning-tree guard root Description The spanning-tree guard root command is used to enable the Root Protect function for a port. With the Root Protect function enabled, the root bridge will set itself automatically as ERROR-PORT when receiving BPDU packets with higher priority, in order to maintain the role of root ridge. To disable the Root Protect function, please use no spanning-tree guard root command. Syntax spanning-tree guard root no spanning-tree guard root Command Mode Interface Configuration Mode (interface ten-gigabitEthernet / interface range ten-gigabitEthernet / interface port-channel / interface range port-channel) Example Enable the Root Protect function for port 2: T1700X-16TS(config)# interface ten-gigabitEthernet 1/0/2 T1700X-16TS(config-if)# spanning-tree guard root 26.21 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.
