Usage Information The RPVST+ protocol determines the root bridge but you can assign one bridge a lower priority to increase the
probability it being the root bridge. A lower priority value increases the probability of the bridge becoming a
root bridge.

OS10(config)# spanning-tree vlan 10 priority 0
Supported Releases 10.2.0E or later
spanning-tree vlan priority (Interface)
