4.2.1 Configuring the TC Protect

Follow these steps to configure TC protect feature for ports:
Step 1 configure
Enter global configuration mode.
Step 2 spanning-tree tc-defend threshold threshold period period
(Except T1600G-18TS) Configure the threshold and cycle of TC protect globally.
threshold:
it is 20. TC threshold is the maximum number of the TC-BPDUs received by the switch in a TC
protect cycle.
pri:
is 5.
Step 3 interface { fastEthernet port | gigabitEthernet port | range gigabitEthernet port-list ] [port-
channel port-channel | range port-channel port-channel-list }
Enter interface configuration mode.
Step 4 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.
Step 5 show spanning-tree interface-security [ fastEthernet port | gigabitEthernet port | port-
channel lagid ] [ bpdufilter | bpduguard | loop | root | tc | tc-defend ]
(Optional) View the protect information of ports.
port:
lagid:
Step 6 end
Return to privileged EXEC mode.
Step 7 copy running-config startup-config
Save the settings in the configuration file.
This example shows how to enable the TC Protect function on port 1/0/3 with the TC
threshold is 25 and the TC Protect Cycle is 8 (demonstrated with T1600G-52TS):
Switch#configure
---------------
Enable
Specify the TC threshold, the valid values ranges from 1 to 100 packets. By default,
Specify the TC protect cycle, the valid values ranges from 1 to 10 in seconds. By default, it
Specify the port number.
Specify the ID of the LAG.
