e.
A ring node accepting an R-APS (MS) message, without any local higher
priority requests stops transmitting R-APS messages.
f.
A ring node receiving an R-APS (MS) message flushes its FDB.
◆
Protection switching on a manual switch request is completed when the above
actions are performed by each ring node. At this point, traffic flows around the
ring are resumed. From this point on, the following rules apply regarding
processing of further manual switch commands:
a.
While an existing manual switch request is present in the ring, any new
manual switch request is rejected. The request is rejected at the ring node
where the new request is issued and a notification is generated to inform
the operator that the new MS request was not accepted.
b.
A ring node with a local manual switch command which receives an R-APS
(MS) message with a different Node ID clears its manual switch request and
starts transmitting R-APS (NR) messages. The ring node keeps the ring port
blocked due to the previous manual switch command.
c.
An ring node with a local manual switch command that receives an R-APS
message or a local request of higher priority than R-APS (MS) clear its
manual switch request. The ring node then processes the new higher
priority request.
