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.
Examples
# Disable the TC-BPDU attack guard function for the device.
<Sysname> system-view
[Sysname] stp tc-protection disable
