Verifying the Ethernet Protection Ring on CS1
Purpose Verify that ERP is enabled on CS1.
Action Show the status of the ring automatic protection switching (R-APS) messages to
determine if there is a ring failure:
user@cs1>show protection-group ethernet-ring aps
Ethernet Ring Name Request/state No Flush Ring Protection Originator Remote
Node ID
Link Blocked
ring-1 NR No Yes Yes
ring-2 NR No Yes No
13:22:af:31:fc:00
Meaning The output displayed shows that protection groups ring-1 and ring-2 have a Request/state
of NR, meaning there is no request for APS on the ring. If a Request/state of SF is displayed,
it indicates there is a signal failure on the ring. The output also shows that the ring
protection link is not blocked. The No Flush field displays No, indicating that MAC
addresses will be flushed when the ring nodes receive this message first time. A value of
Yes would indicate MAC address flushing is not needed. The Originator field for ring-1
displays yes, indicating that this node is an R-APS originator.
Verifying the Data Channel CS1
Purpose Verify the forwarding state of the data channel.
Action List the interfaces acting as the control channels and their respective data channels
(represented by the Spanning Tree Protocol (STP) index number):
user@cs1>show protection-group ethernet-ring data-channel
Ethernet ring data channel parameters for protection group ring-1
Interface STP index Forward State
ge-3/2/4 122 forwarding
ge-5/2/3 123 forwarding
Ethernet ring data channel parameters for protection group ring-2
Interface STP index Forward State
