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
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
device can perform within a certain period of time after receiving the first
TC-BPDU.
