Ethernet Ring Protection Switching
– 501 –
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.
■
Recovery for manual switching under revertive and non-revertive
mode is described under the Revertive parameter.
■
Clear – Manually clears the protection state which has been invoked by a
forced switch or manual switch command, and the node is operating under
non-revertive mode; or before the WTR or WTB timer expires when the
node is operating in revertive mode.
■
Two steps are required to make a ring operating in non-revertive mode
return to Idle state from forced switch or manual switch state:
1. Issue a Clear command to remove the forced switch command on
the node where a local forced switch command is active.
2. Issue a Clear command on the RPL owner node to trigger the
reversion.
■
The Clear command will also stop the WTR and WTB delay timers and
reset their values.
■
More detailed information about using this command for non-revertive
mode is included under the Revertive parameter. (See the Command
Usage section under “ERPS Instance Configuration” on page 483.)
Web Interface
