Command Mode Usage Information Example (RSTP) CONFIGURATION All STP instances are stopped in the previous STP mode, and are restarted in the new mode. You can also change to RSTP/MST mode. OS10(config)# spanning-tree mode rstp Example (MST) OS10(config)# spanning-tree mode mst Supported Releases 10.2.0E or later spanning-tree port Sets the port type as the EdgePort. Syntax spanning-tree port type edge Parameters None Default Not configured Command Mode INTERFACE Usage Information When you configure an EdgePort on a device running STP, the port immediately transitions to Forwarding state. Only configured ports connected to end hosts act as EdgePorts. Example OS10(config)# spanning-tree port type edge Supported Releases 10.2.0E or later spanning-tree vlan cost Sets the path cost of the interface per VLAN for PVST calculations. Syntax spanning-tree vlan vlan-id cost {value} Parameters value - Enter a port cost value to set the path cost of the interface for PVST calculations (1 to 200000000). Defaults • 100- Mb/s Ethernet interface = 200000 • 1 Gigabit Ethernet interface = 20000 • 10-Gigabit Ethernet interface = 2000 • Port-channel interface with one 100 Mb/s Ethernet = 200000 • Port-channel interface with one 1 Gigabit Ethernet = 20000 • Port-channel interface with one 10 Gigabit Ethernet = 2000 • Port-channel with two 1 Gigabit Ethernet = 18000 • Port-channel with two 10 Gigabit Ethernet = 1800 • Port-channel with two 100 Mbps Ethernet = 180000 Command Mode Usage Information Example INTERFACE The media speed of a LAN interface determines the STP port path cost default value.
