The same commands must be issued against the other N3024 (N3024-2 in Figure 9) except setting VLANs
30-32 with a priority of 4096 and VLANs 33-35 with a priority of 1. This will result in the first N3024 being the
root bridge for VLANs 30 through 32 while the second switch will be the root bridge for VLANs 33-35. Below is
spanning tree output for VLANs 30 and 33 on the second N3024.
