TC Protection
Enable or disable TC-BPDU guard.
When receiving topology change (TC) BPDUs, the device flushes its forwarding
address entries. If someone forges TC-BPDUs to attack the device, the device will
receive a large number of TC-BPDUs within a short time and frequently flushes its
forwarding address entries. This affects network stability.
With the TC-BPDU guard function, you can prevent frequent flushing of forwarding
address entries.
IMPORTANT:
HP does not recommend you to disable this function.
TC Protection Threshold
Set the maximum number of immediate forwarding address entry flushes the device
can perform within a certain period of time after receiving the first TC-BPDU.
