I have a ring with four IE3000-8TC switches Sw1, Sw2, Sw3, Sw4
They are configured in this way:
____________________________
Sw1
rep admin vlan 997
int gi1/1
sw mode trunk
rep segment 1 edge primary
int gi1/2
sw mode trunk
rep segment 1 edge
____________________________
Sw2
rep admin vlan 997
int gi1/1
sw mode trunk
rep segment 1
int gi1/2
sw mode trunk
rep segment 1
_____________________
Sw3
rep admin vlan 997
int gi1/1
sw mode trunk
rep segment 1
int gi1/2
sw mode trunk
rep segment 1
______________________
Sw4
rep admin vlan 997
int gi1/1
sw mode trunk
rep segment 1
int gi1/2
sw mode trunk
rep segment 1
The connections are showed in the image attacched, when all conections are working fine rep doesnt have problems and i show the rep topology like this
SW1#sh rep topology
REP Segment 1
BridgeName PortName Edge Role
---------------- ---------- ---- ----
SW1 Gi1/1 Pri Open
SW2 Gi1/1 Open
SW2 Gi1/2 Open
SW3 Gi1/1 Open
SW3 Gi1/2 Open
SW4 Gi1/1 Open
SW4 Gi1/2 Alt
SW1 Gi1/2 Sec Open
But if i disconnect a link in the sw3 the rep topology show the next output and the convergence doesnt works
SW1#sh rep topology
REP Segment 1
Warning: REP detects a segment failure, topology may be incomplete
BridgeName PortName Edge Role
---------------- ---------- ---- ----
SW1 Gi1/1 Sec Open
SW2 Gi1/1 Open
SW2 Gi1/2 Open
SW3 Gi1/1 Open
SW4 Gi1/2 Fail
Why I have lost the direct link between SW1 and SW4??

I have quite same this problem but it occurs on ME3400 ring. I went to SW that show fail, shutdown and no shutdown the failed interface. It’s work. But I don’t know why?
System image file is "flash:me340x-metroipaccessk9-mz.122-53.SE.bin"
ac3400combo(config)#int gi0/16
ac3400combo(config-if)#shu
ac3400combo(config-if)#
005830: Feb 16 14:26:45.074 bkk: %REP-4-LINKSTATUS: GigabitEthernet0/16 (segment 1) is non-operational due to port become non-trunk

ac3400combo#
005835: Feb 16 14:27:16.480 bkk: %REP-4-LINKSTATUS: GigabitEthernet0/16 (segment 1) is operational
Thank you very much.

Had this problem in a lab I configured today also. Did you have any luck resolving this?
I've a stacked 3750X with 2x IE-3000 access switches in a REP ring.
SW1 Gi1/0/1 Pri Open
SW2 Gi1/1 Open
SW2 Gi1/2 Open
SW3 Gi1/1 Open
SW3 Gi1/2 Open
SW1 Gi2/0/1 Sec Alt
REP works fine if I remove the open link connected to the primary edge port. However if I remove the trunk link between the 2x IE-3000 access switches, REP does not converge.
