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 Theoutput displayedshows the STP index number used byeach interface in ring instances
ring-1and ring-2. The STP index controls the forwardingbehavior for a set of VLANs on
thedata channel of a ring instanceon a ring interface. For ring instances, there aremultiple
STPindex numbers (here representing VLANs 200, 300, 500,and 600). The Forward
Stateshowswhether the data channel is forwarding or discarding traffic.All data channels
areforwarding traffic.
Verifyingthe VLANs on AS1
Purpose Verifythe data channel logical interfacesand the VLAN IDs controlled by a ring instance
datachannel.

Meaning Theoutput displayedshows the ring interfacesge-2/0/5 and ge-2/1/ 1 in protectiongroups
ring-1and ring-2. For ring-1, VLAN 200 and VLAN 300 are being supported on both STP
Index22 and 23 on bridge domains bd200 and bd300. For ring-2, VLAN 500 and VLAN
600are being supported on both STP Index 24 and 25 on bridge domains bd500 and
bd600.The datachannel controls the traffic on the VLAN IDs to facilitateload-balancing.
