Interface Vlan STP Index Bridge Domain
ge-2/0/4 500 46 default—switch/bd500
ge-2/0/8 500 47 default-switch/bd500
ge-2/0/4 600 46 default—switch/bd600
ge-2/0/8 600 47 default-switch/bd600
Meaning
The output displayed shows the ring interfaces
ge-2/0/4
and
ge-2/0/8
in protection
groups
ring-1
and
ring-2
. For
ring-1
, VLAN 200 and VLAN 300 are being supported on both
STP Index 44
and
45
on bridge domains
bd200
and
bd300
. For
ring-2
, VLAN 500 and
VLAN 600 are being supported on both
STP Index 46
and
47
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 AS1
Purpose
Verify that ERP is enabled on AS1.
Action
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
Ethernet Ring Name Request/state No Flush Ring Protection Originator Remote
Node ID
Link Blocked
Ring-1 NR No Yes No
00:21:59:03:ff:d0
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
and
ring-2
displays
No
, indicating that this node is not the R-APS originator.
Verifying the Data Channels on AS1
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 STP index number):
user@as1>
show protection-group ethernet-ring data-channel
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
