HP Configuring MSTP on a port

Item	Description
	Selects whether to enable 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
tc-protection	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.
	HP recommends not disabling this function.
	Sets the maximum number of immediate forwarding address entry flushes the
tc-protection threshold	device can perform within a certain period of time after receiving the first
	TC-BPDU.
