Displaying And Maintaining Mstp - HP 4800G Series Configuration Manual

With the TC-BPDU guard function, you can set the maximum number of immediate forwarding address
entry flushes that the switch can perform within a certain period of time after receiving the first TC-BPDU.
For TC-BPDUs received in excess of the limit, the switch performs forwarding address entry flush only
when the time period expires. This prevents frequent flushing of forwarding address entries.
Follow these steps to enable TC-BPDU guard:
To do...
Enter system view
Enable the TC-BPDU guard
function
Configure the maximum
number of forwarding address
entry flushes that the device
can perform within a specific
time period after it receives the
first TC-BPDU
We recommend that you keep this feature enabled.
