Usage guidelines

With TC-BPDU guard, you can set the maximum number of immediate forwarding address entry flushes that the device can perform 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.

Examples

# Disable TC-BPDU attack guard for the device.

<Sysname> system-view
[Sysname] undo stp tc-protection
