Usage guidelines With the TC-BPDU guard function, you can set the maximum number of immediate forwarding address entry flushes that the device can perform within a certain interval (every 10 seconds). For TC-BPDUs received that exceed the limit, the device performs a forwarding address entry flush when the interval elapses. This prevents frequent flushing of forwarding address entries.
