Connectivity Guide

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 inuences 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
