spanning-tree port-priority
This command configures the priority for the specified interface. Use the no form to restore the default.
Syntax
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
128
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

spanning-tree edge-port
This command specifies an interface as an edge port. Use the no form to restore the default.
Syntax
[no] spanning-tree edge-port
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• You can enable this option if an interface is attached to a LAN segment that is at the end of a bridged LAN or to an end
node. Since end nodes cannot cause forwarding loops, they can pass directly through to the spanning tree forwarding
state. Specifying Edge Ports provides quicker convergence for devices such as workstations or servers, retains the
current forwarding database to reduce the amount of frame flooding required to rebuild address tables during
reconfiguration events, does not cause the spanning tree to initiate reconfiguration when the interface changes state, and
