Verifying the Ethernet Protection Ring on AS1
Verify that ERP is enabled on AS1.
Show the status of the ring APS (R-APS) messages to determine if there is a ring failure:
user@as1> show protection-group ethernet-ring aps

Ring-1 NR
00:21:59:03:ff:d0
Ring-2 NR

The output displayed shows that protection groups
of , meaning there is no request for APS on the ring. If a
NR
it indicates there is a signal failure on the ring. The output also shows that the ring
protection link is not blocked. The
addresses will be flushed when the ring nodes receive this message first time. A value of
would indicate MAC address flushing is not needed. The

Verifying the Data Channels on AS1
Verify the forwarding state of the data channel.
