16. ERPS
This page lets you set and view ERPS instances.
The switch supports ITU-T
Ethernet Ring Protection Switching. Recommendation ITU-T G.8032/Y.1344
defines the automatic protection switching (APS) protocol and protection switching mechanisms for Ethernet
layer network (ETH) ring topologies. Included are details on Ethernet ring protection characteristics,
architectures and the ring APS (R-APS) protocol.

RPL Mode
:
The
Ring Protection Link mode. Possible values are:
None
: There is no link.
Owner
: The
Ring Protection Link mode is “Owner”.
Neighbor
: The

VC
: Controls whether to use a Virtual Channel with a sub-ring.
Interconnect Instance
: For a sub-ring on an interconnection node, this must reference the instance ID of the
ring to which this sub-ring is connected.
Interconnect Prop
: Controls whether the ring referenced by Interconnect Instance will propagate R-APS flush
PDUs whenever this sub-ring's topology changes.
Port0/Port1 Interface
: Interface index of ring protection Port0/Port1.
