Stp Interface Transmit-Limit - Huawei Quidway S8500 Series Command Manual

Command Manual – STP
Quidway S8500 Series Routing Switches
Root protection function is used against such problem. The port configured with Root
protection only plays a role of designated port on every instance. Whenever such port
receives a higher-priority BPDU, that is, it is about to turn into non-designated port, it
will be set to listening state and not forward packets any more (as if the link to the port is
disconnected). So, Root protection takes effect only when it is enabled on a designated
port. If the port has not received any higher-priority BPDU for a certain period of time
thereafter, it will resume its original state.

interface-number parameters, refer to the corresponding descriptions in Port
Command Manual. &<1-10> means that the preceding parameters can be entered up
to 10 times.
packetnum: Maximum number of configuration BPDUs that can be transmitted via the
port per Hello Time, ranging from 1 to 255 (expressed as a counter value without any
