Command Usage
• Each spanning-tree instance is associated with a unique set of VLAN
IDs.
• This command is used by the multiple spanning-tree algorithm to
determine the best path between devices. Therefore, lower values
should be assigned to interfaces attached to faster media, and higher
values assigned to interfaces with slower media.
• Path cost takes precedence over interface priority.
