Stp Tc-Protection Threshold; Stp Timer Forward-Delay - H3C MSR Series Command Reference Manual

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 every a certain period of time (10 seconds). For
TC-BPDUs received in excess of the limit, the device performs a forwarding address entry flush
when the time period expires. This prevents frequent flushing of forwarding address entries.

# Disable the TC-BPDU attack guard function for the device.
