Explanation:
Note that it is fine to use the spanning-tree priority command and the spanning-tree pseudo-information command together, but the root priority in the pseudo-information needs to be a lower value (higher priority) than the spanning-tree priority to make sure that the remaining working Cisco FabricPath switch is sending a superior BPDU with the common FabricPath bridge ID and the configured spanning-tree pseudo-information priority and remains at the spanning-tree root.
