Stp Bridge-Diameter - H3C S6550X-HI Series Command Reference Manual

Usage guidelines
With BPDU guard enabled, the device shuts down an edge port and notifies the NMS of the
shutdown event when the edge port receives configuration BPDUs.
The device reactivates the ports that have been shut down when the port status detection timer
expires. You can set this timer by using the
about this command, see device management commands in System Management Command
Reference.
The
stp bpdu-protection
stp edged-port
You can configure the BPDU guard feature in system view or on a per-edge port basis. An edge port
preferentially uses the port-specific BPDU guard setting. If the port-specific BPDU guard setting is
not available, the edge port uses the global BPDU guard setting.
