ge-3/2/4 124 discarding
ge-5/2/3 125 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.
Verifying the VLANs on CS1
Purpose
Verify the data channel logical interfaces and the VLAN IDs controlled by a ring instance
data channel.
Action
List dynamic VLAN membership:
user@cs1>
show protection-group ethernet-ring vlan
Ethernet ring IFBD parameters for protection group ring-1
Interface Vlan STP Index Bridge Domain
ge-3/2/4 200 122 vs/bd200
ge-5/2/3 200 123 vs/bd200

ge-3/2/4 600 124 vs/bd600
ge-5/2/3 600 125 vs/bd600
Meaning
The output displayed shows the ring interfaces
ge-3/2/4
and
ge-5/2/3
in protection
groups
ring-1
and
ring-2
. For
ring-1
, VLAN 200 and VLAN 300 are being supported on both
STP Index 122
and
123
on bridge domains
bd200
and
bd300
. For
ring-2
, VLAN 500 and
VLAN 600 are being supported on both
STP Index 124
and
125
on bridge domains
bd500
and
bd600
. The data channel controls the traffic on the VLAN IDs to facilitate load
balancing.
Verifying the Ethernet Protection Ring on CS2
Purpose
Verify that ERP is enabled on CS2.
Action
Show the status of the ring APS (R-APS) messages to determine if there is a ring failure:
