Item Description
tc-protection
Select 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
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.
NOTE:
HP recommends not disabling 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.
