The output displayed shows that protection groups
of NR , meaning there is no request for APS on the ring. If a

The output displayed shows the STP index number used by each interface in ring instances
ring-1 and ring-2 . The STP index controls the forwarding behavior for a set of VLANs on
the data channel of a ring instance on a ring interface. For ring instances, there are multiple
STP index numbers (here representing VLANs 200, 300, 500, and 600). The
