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
State shows whether the data channel is
are forwarding traffic.
Verifying the VLANs on AS1
Verify the data channel logical interfaces and the VLAN IDs controlled by a ring instance
data channel.
List dynamic VLAN membership:
