Configuring Spanning Tree STP Security Configurations When you enable TC Protect function on ports, set the TC threshold and TC Protect Cycle here. If the number of the received TC-BPDUs exceeds the maximum number you set in the TC threshold field, the switch will not remove MAC address entries in the TC protect cycle. Choose the menu Spanning Tree > STP Security > TC Protect to load the following page. Figure 4-2 Configuring the TC Protect Configure the parameters of TC Protect feature, and click Apply. TC Threshold Enter a number from 1 to 100, and the default value is 20. It is the maximum number of the TC-BPDUs received by the switch in a TC Protect Cycle. TC Protect Cycle Enter a value from 1 to 10 to specify the TC Protect Cycle. The default value is 5. 4.2 Using the CLI 4.2.1 Configuring the STP Security Follow these steps to configure the Root protect feature, BPDU protect feature and BPDU filter feature for ports: Step 1 Step 2 Step 3 configure Enter global configuration mode. interface {gigabitEthernet port | range gigabitEthernet port-list] [port-channel port-channel | range port-channel port-channel-list} Enter interface configuration mode. spanning-tree guard loop (Optional) Enable the Loop Protect feature on the port. t is recommended to enable this function on root ports and alternate ports. Loop Protect function is used to prevent loops caused by link congestions or link failures. With Loop Protect function enabled, the port will temporarily transit to blocking state when it does not receive BPDUs. After the link restores to normal, the port will transit to its normal state, so loops can be prevented. Configuration Guide 329
