Ethernet Ring Protection Switching
– 456 –
a.
The RPL Owner Node does not generate a response on reception of
an R-APS (NR) messages.
b.
When other healthy ring nodes receive the NR (Node ID) message,
no action is taken in response to the message.
c.
When the operator issues the Clear command (Configure
Operation page) for non-revertive mode at the RPL Owner Node,
the non-revertive operation is cleared, the RPL Owner Node blocks
its RPL port, and transmits an R-APS (NR, RB) message in both
directions, repeatedly.
d.
Upon receiving an R-APS (NR, RB) message, any blocking node
should unblock its non-failed ring port. If it is an R-APS (NR, RB)
message without a DNF indication, all ring nodes flush the FDB.
■
Recovery for Forced Switching – A Forced Switch command is
removed by issuing the Clear command (Configure Operation
page) to the same ring node where Forced Switch mode is in
effect. The clear command removes any existing local operator
commands, and triggers reversion if the ring is in revertive
behavior mode.
The ring node where the Forced Switch was cleared continuously
transmits the R-APS (NR) message on both ring ports, informing
other nodes that no request is present at this ring node. The
ring nodes stop transmitting R-APS (NR) messages when they
accept an RAPS (NR, RB) message, or when another higher
priority request is received.
If the ring node where the Forced Switch was cleared receives
an R-APS (NR) message with a Node ID higher than its own
Node ID, it unblocks any ring port which does not have an SF
condition and stops transmitting R-APS (NR) message over both
ring ports.
■
Recovery with revertive mode is handled as follows:
a.
The reception of an R-APS (NR) message causes the RPL Owner
Node to start the WTB timer.
b.
The WTB timer is cancelled if during the WTB period a higher
priority request than NR is accepted by the RPL Owner Node or
is declared locally at the RPL Owner Node.
c.
When the WTB timer expires, in the absence of any other higher
priority request, the RPL Owner Node initiates reversion by
blocking the traffic channel over the RPL, transmitting an R-APS
(NR, RB) message over both ring ports, informing the ring that
the RPL is blocked, and flushes the FDB.
d.
The acceptance of the R-APS (NR, RB) message causes all ring
nodes to unblock any blocked non-RPL that does not have an
SF condition. If it is an R-APS (NR, RB) message without a DNF
indication, all ring nodes flush their FDB. This action unblocks
