sub-ring
Syntax sub-ring {virtual-link | non-virtual-link}
[no] sub-ring
Context config>eth-ring>sub-ring
This command specifies this ring-id to be sub-ring as defined in G.8032. By declaring the ring as a sub-ring
object, the ring will only have one valid path and the sub-ring will be connected to a major ring or a VPLS
instance. The virtual-link parameter declares that a sub-ring is connected to another ring and that control
messages can be sent over the attached ring to the other side of the sub-ring. The non-virtual channel
parameter declares that a sub-ring may be connected to a another ring or to a VPLS instance but that no
control messages from the sub-ring use the attached ring or VPLS instance. The non-virtual channel
behavior is standard G.8032 capability.
The no form of this command deletes the sub-ring and its virtual channel associations.
Default
no sub-ring
Parameters virtual-link — Specifies the interconnection is to a ring and a virtual link will be used.
non-virtual-link — Specifies the interconnection is to a ring or a VPLS instance and a virtual link will not be
used.

This command links the G.8032 sub-ring to a ring instance or to a VPLS instance. The ring instance must be
a complete ring with two paths but may itself be a sub-ring or a major ring (declared by its configuration on
