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
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).
Default Setting
Floods to all other ports in the same VLAN.
