Command Usage
Bridge priority is used in selecting the root device, root port, and designated port. The device with
the highest priority (i.e., lower numeric value) becomes the STA root device. However, if all devices
have the same priority, the device with the lowest MAC address will then become the root device.
Example
Console(config)#spanning-tree priority 40000
Console(config)#
spanning-tree mst configuration
This command changes to Multiple Spanning Tree (MST) configuration mode.
Default Setting
No VLANs are mapped to any MST instance.
The region name is set the switch’s MAC address.

spanning-tree system-bpdu-flooding
This command configures the system to flood BPDUs to all other ports on the switch or just to all
other ports in the same VLAN when spanning tree is disabled globally on the switch or disabled on
a specific port. Use the no form to restore the default.
Syntax
spanning-tree system-bpdu-flooding {to-all | to-vlan}
no spanning-tree system-bpdu-flooding
to-all - Floods BPDUs to all other ports on the switch.
to-vlan - Floods BPDUs to all other ports within the receiving port’s native VLAN (i.e., as
determined by port’s PVID).
