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
