Configuring STP Interface Settings Beginning in Privileged EXEC mode, use the following commands to configure the STP settings for a specific interface. Command configure interface interface spanning-tree disable spanning-tree portpriority priority spanning-tree cost cost CTRL + Z show spanning-tree interface Purpose Enter global configuration mode. Enter interface configuration mode for the specified interface. The interface variable includes the interface type and number, for example gigabitethernet 1/0/3 or portchannel 4. You can also specify a range of interfaces with the interface range command, for example, interface range gigabitethernet 1/0/8-12 configures interfaces 8, 9, 10, 11, and 12. The range keyword is also valid for LAGs (port channels). Disable spanning-tree on the port. Specify the priority of the port. (Range: 0-240). The priority value is used to determine which ports are put in the forwarding state and which ports are put in the blocking state. A port with a lower priority value is more likely to be put into a forwarding state. Specify the spanning-tree path cost for the port. (Range: 0-200,000,000). The default cost is 0, which signifies that the cost is automatically calculated based on port speed. Exit to Privileged EXEC mode. View spanning tree configuration information for the specified port or LAG (port channel). Configuring the Spanning Tree Protocol 651
