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

TC Protection

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.
