Ethernet ring data channel parameters for protection group ring-1
Interface STP index Forward State
ge-2/0/5 22 forwarding
ge-2/1/1 23 forwarding
Ethernet ring data channel parameters for protection group ring-2
Interface STP index Forward State
ge-2/0/5 24 forwarding
ge-2/1/1 25 forwarding
Meaning 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 Forward
State shows whether the data channel is forwarding or discarding traffic. All data channels
are forwarding traffic.
Verifying the VLANs on AS1
Purpose Verify the data channel logical interfaces and the VLAN IDs controlled by a ring instance
data channel.
Action List dynamic VLAN membership:

Ethernet ring IFBD parameters for protection group ring-1
Interface Vlan STP Index Bridge Domain
ge-2/0/5 200 22 default-switch/bd200
ge-2/1/1 200 23 default-switch/bd200
ge-2/0/5 300 22 default-switch/bd300
ge-2/1/1 300 23 default-switch/bd300
Ethernet ring IFBD parameters for protection group ring-2
Interface Vlan STP Index Bridge Domain
ge-2/0/5 500 24 default-switch/bd500
ge-2/1/1 500 25 default-switch/bd500
ge-2/0/5 600 24 default-switch/bd600
ge-2/1/1 600 25 default-switch/bd600
Meaning The output displayed shows the ring interfaces ge-2/0/5 and ge-2/1/1 in protection groups
ring-1 and ring-2. For ring-1, VLAN 200 and VLAN 300 are being supported on both STP
Index 22 and 23 on bridge domains bd200 and bd300. For ring-2, VLAN 500 and VLAN
600 are being supported on both STP Index 24 and 25 on bridge domains bd500 and
bd600. The data channel controls the traffic on the VLAN IDs to facilitate load-balancing.
