spanning-tree pathcost-type

Description

Configures the spanning tree path cost type. The long mode provides support for the wider range of link speeds required by high-speed interfaces. All switches in the network must use the same path cost type or errors can occur in the spanning tree.

The no form of this command sets the spanning tree path cost type to the default value of long.
