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.

spanning-tree port-priority priority

no spanning-tree port-priority

priority - The priority for a port. (Range: 0-240, in steps of 16)

Default Setting

Command Mode

Interface Configuration (Ethernet, Port Channel)

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
