set spantree root
These examples show that setting the bridge priority to 8192 was not sufficient to make this switch the
root. The priority was further reduced to 7192 (100 less than the current root switch) to make this switch
the root switch. However, reducing it to this value did not make it the root switch for active VLANs 16
and 17.
