idle: Clears forced switchover or manual switchover and enters Idle state.
ringlet0: Requests switchover in Ringlet0.
ringlet1: Requests switchover in Ringlet1.
Description
Use the rpr admin-request fs command to generate a forced switchover request,
making the node enter forced switchover status. The event related to switchover in
protection mechanism includes FS, SF, SD, MS, WTR and IDLE. Other protection
requests are not able to preempt FS with the highest priority. After you use the rpr
admin-request fs command to generate an FS request, other events are not able to
preempt FS. To cancel FS, you must use the rpr admin-request idle command.
Use the rpr admin-request ms command to generate an MS for manual switchover.
The MS priority is lower. Both the rpr admin-request idle command and any failure
(FS, SF or SD) in the RPR ring can preempt MS, making MS fail. If there are other
commands with higher priority, the manual switchover you are performing also fails
automatically.
Use the rpr admin-request idle command to clear forced switchover or manual
switchover.
Note that the receiving and sending sub-rings of port 1 on the panel are Ringlet0 and
Ringlet1 respectively. The receiving and sending sub-rings of port 2 on the panel are
Ringlet1 and Ringlet0 respectively. Here Ringlet0 and Ringlet1 are both receiving
sub-rings.
