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, from 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 = 10000
Port-channel with two 10 Gigabit Ethernet = 1000
Port-channel with two 100 Mbps Ethernet = 100000

Command Mode

INTERFACE

Usage Information

The media speed of a LAN interface determines the STP port path cost default value.

Example

OS10(conf-if-eth1/1/4)# spanning-tree vlan 10 cost 1000
