Command Usage
•
When enabled, BPDUs are flooded to all other ports on the switch or to all other ports within
the receiving port’s native VLAN as specified by the
spanning-tree system-bpdu-flooding
command.
•
The
spanning-tree system-bpdu-flooding
command has no effect if BPDU flooding is disabled
on a port by the spanning-tree port-bpdu-flooding command.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree port-bpdu-flooding
Console(config-if)#
spanning-tree port-priority
This command configures the priority for the specified interface. Use the no form to restore the
default.

Command Usage
•
This command defines the priority for the use of a port in the Spanning Tree Algorithm. If the
path cost for all ports on a switch are the same, the port with the highest priority (that is,
lowest value) will be configured as an active link in the spanning tree.
•
Where more than one port is assigned the highest priority, the port with lowest numeric
identifier will be enabled.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree port-priority 0
