an R-APS (NR, RB) message without a DNF indication, all Ethernet Ring
Nodes flush their FDB. This action unblocks the ring port which was
blocked as a result of an operator command.
■
Recovery with non-revertive mode is handled in the following way:
a. The RPL Owner Node, upon reception of an R-APS (NR) message and in
the absence of any other higher priority request does not perform any
action.
b. Then, after the operator issues the erps clear command at the RPL
Owner Node, this ring node blocks the ring port attached to the RPL,
transmits an R-APS (NR, RB) message over both ring ports, informing
the ring that the RPL is blocked, and flushes its FDB.
c. The acceptance of the R-APS (NR, RB) message triggers all ring nodes to
unblock any blocked non-RPL which 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 the ring port which was blocked as
result of an operator command.
