Usage Information
The cost value is based on the interface type. The greater the cost value, the less likely the port is selected to be a forwarding port. The priority influences the likelihood that a port is selected to be a forwarding port if several ports have the same cost value.
Example 
OS10(conf-if-eth1/1/1)# spanning-tree msti 1 priority 0
OS10(conf-if-eth1/1/1)# spanning-tree msti 1 cost 3
