Ring Protection (ERP) instance as a sub-ring.

normal fully enclosed ring.

Default By default the mode is no sub-ring.
Mode G8032 Configure Switch
Usage notes An ERP instance can operate normally as a fully enclosed ring, commonly called a
major ring, or as a partially enclosed ring, called a sub-ring. Sub-rings must be
attached to either a major ring (one that is fully closed) or to other sub-rings where
one of the other sub-rings itself is attached to a major ring.
Setting the mode to sub-ring should also be set for all nodes in the sub-ring, as the
G.8032 state machine is different from that of a major ring.
This configuration can only be accepted when the ERP instance is disabled.
When the physical ring instance used by this ERP instance is configured for
terminating interface, then this ERP instance will automatically be configured to be
in the sub-ring mode and can not be changed.
Example To configure an ERP instance named “blue” as a sub-ring, use the following
commands:
awplus(config)# g8032 erp-instance blue
awplus(g8032-config-switch)# sub-ring
