Default STP Priority on Huawei Switches | Generated by AI
Question: On a Huawei switch, what is the default priority value of STP (Spanning Tree Protocol)?
A) 0
B) 4096
C) 32768
D) 61440
Answer:
The correct answer is C) 32768.
This is the default bridge priority value for the device in STP/RSTP/MSTP on Huawei switches. The bridge priority forms the higher part of the Bridge ID (BID), and a lower value increases the likelihood of the switch becoming the root bridge. Priorities must be multiples of 4096, ranging from 0 to 61440.
- 0 is set when configuring the switch as the primary root bridge (using
stp root primary). - 4096 is set for the secondary root bridge (using
stp root secondary). - 61440 is the maximum possible priority (least likely to be root).
Official Huawei documentation and configuration guides consistently confirm 32768 as the default.
