Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 configure Enter global configuration mode. spanning-tree tc-defend threshold threshold period period Configure the TC Protect function globally. threshold: Specify the TC threshold, the valid values ranges from 1 to 100 packets. By default, it is 20. TC Threshold is the maximum number of the TC-BPDUs received by the switch in a TC Protect cycle. pri: Specify the TC Protect cycle, the valid values ranges from 1 to 10 in seconds. By default, it is 5. interface { fastEthernet port | gigabitEthernet port | range gigabitEthernet port-list] [portchannel port-channel | range port-channel port-channel-list} Enter interface configuration mode. spanning-tree guard tc Enable the TC Protect function on the port. TC Protect is to prevent the decrease of the performance and stability of the switch brought by continuously removing MAC address entries upon receiving TC-BPDUs in the network. show spanning-tree interface-security [ fastEthernet port | gigabitEthernet port | portchannel lagid ] [ bpdufilter | bpduguard | loop | root | tc | tc-defend ] (Optional) View the protect inforamtion of ports. port: Specify the port number. lagid: Specify the ID of the LAG. end Return to privileged EXEC mode.
